Eliminative Ring Fission of 4-Acyl-2,3-dihydro-4H-1,4-benzothiazines

The behavior of 4-acyl-2,3-dihydro-1,4-benzothiazines 1-11 upon treatment with lithium diisopropylamide (LDA) in THF at -78 deg C has been examined.Very marked differences have been observed.Whereas unsubstituted and monosubstituted derivatives (1-4) readily undergo “eliminative ring fission”, providing 2-(alkylthio)phenylenamides 12, 2-aminophenyl vinyl sulfides 16, and 3-acylbenzothiazolines 13, 2,3-disubstituted derivatives (5-7) do not react at all.The relationship between structural features of the above-mentioned dihydrobenzothiazines and their reactivity is considered.Lithium ion plays a fundamental role in providing activation for the ring-opening reaction.

Development of high-affinity 5-HT3 receptor antagonists. Structure- affinity relationships of novel 1,7-annelated indole derivatives. 1

On the basis of the structures of ondansetron and GR 65,630, its ring- opened C-linked methylimidazole analogue, novel 1,7-annelated indole derivatives were synthesized as potential 5-HT3 antagonists. Receptor binding studies show that all compounds display a high affinity for the 5- HT3 receptors. In both series annelation results in compounds being 7 and 4 times more potent than the references ondansetron and GR 65,630, respectively. Similar to ondansetron, the 1,7-annelated indoles show little stereoselectivity. The (-)-isomers are only slightly more potent than the (+)-isomers. The receptor binding profile of l-10-[(2-methyl-1H-imidazol-1- yl)methyl]-5,6,8,9,10,11-hexahydro-4H-pyrido[3,2,1-jk]carbazol-11-one hydrochloride (24b) (INN cilansetron) shows that the compound displays, besides a high affinity for 5-HT3 receptors (K(i) = 0.19 nM), a weak affinity for sigma-receptors (K(i) = 340 nM), muscarine M1 receptors (K(i) = 910 nM), and 5-HT4 receptors (K(i) = 960 nM) and no affinity (K(i) ? 5000 nM) for all the other receptor types tested (n = 37). The new compounds fit the proposed necessary chemical template for binding: a heteroaromatic ring system, a coplanar carbonyl group, and a nitrogen center at well-defined distances. The enhanced potency of the annelated 1,7-indole derivatives indicates that the extra ring provides a favorable hydrophobic area for interaction with the 5-HT3 receptor site. In vivo cilansetron is more potent and induces less central side effects than ondansetron. At present cilansetron is in clinical trials.

Process for ortho-cyanation of phenols or phenylamines

A process for ortho-cyanation of phenols or phenylamines which comprises reacting a phenyl compound having hydroxy or optionally substituted amino or cyclic amino, of which ortho position is vacant, with trichloroacetonitrile, C1 -C5 alkyl thiocyanate or C6 -C12 aryl thiocyanate in the presence of a boron trihalide and treating the resultant product with an alkali is provided, and said process is useful in the synthesis of intermediates for medicinals or pesticides.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Synthetic Route of 3080-99-7, you can also check out more blogs aboutSynthetic Route of 3080-99-7

Clinical efficacy of photodynamic therapy and laser irradiation as an adjunct to open flap debridement in the treatment of chronic periodontitis: A systematic review and meta-analysis

Background: The aim of this systematic review and meta-analyses was to assess the quality of evidence and efficacy of antimicrobial photodynamic therapy (aPDT) and laser irradiation (LI) as an adjunct to open flap debridement (OFD) in the treatment of chronic periodontitis. Methods: Electronic searches were conducted in databases (MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials and Cochrane Oral Health Group Trials Register databases) up to March 2019. Randomized clinical trials (RCTs) comparing clinical efficacy of either aPDT and/or LI, placebo, or no treatment were included. Primary outcomes included clinical attachment level (CAL), while secondary outcomes were reduction in probing depth (PD) and gingival recession (GR) depth. The weighted mean differences (WMD) of outcomes and 95% confidence intervals (CI) for each variable were calculated using random effect model. Results: Six RCTs were included. For aPDT studies, the overall mean difference for CAL gain (WMD?=??0.61, 95% CI?=??1.22 to ?0.016, P?=.044) and PD reduction (WMD?=??1.79, 95% CI?=??3.44 to ?0.14, P?=.034) was significant between aPDT and OFD groups at follow-up. No significant overall mean difference was observed for GR depth (WMD?=?0.02, 95% CI?=??0.75 to 0.79, P?=.95). For LI studies, none of the clinical periodontal parameters including CAL gain (WMD?=?0.23, 95% CI?=??0.09 to 0.55, P?=.159, Figure 3A), PD reduction (WMD?=?0.31, 95% CI?=??0.67 to 1.31, P?=.52, Figure 3B) and GR depth (WMD?=??0.34, 95% CI?=??2.47 to 1.78, P?=.74, Figure 3C) were found to be significant between LI and OFD groups at follow-up. Conclusion: With the limited data available, only aPDT as an adjunct to OFD showed superior results for clinical periodontal parameters compared to OFD alone in the treatment of chronic periodontitis. Further RCTs are warranted in order to obtain robust conclusions with regard to laser therapy.

Aromatic Ring Bromination in 1,4-Benzothiazines, 1,4-Benzoxathianes and 1,4-Benzodithianes: the Occurrence of Vicarious Nucleophilic Substitution of Hydrogen and Electrophilic Aromatic Substitution Mechanisms

1,4-benzodithianes, 1,4-benzothiazines and 1,4-benzoxathianes, when treated with bromine in anhydrous chloroform, undergo regiospecific monobromination at the aromatic ring.Based on semiempirical quantum mechanical calculations, the regiochemistry of the reaction in the case of 1,4-benzothiazines and 1,4-benzoxathianes was shown to be consistent with a charge-controlled electrophilic aromatic substitution reaction where the Br+ species comes from monobromosulfonium ions (as 2).On the contrary, in the case of 1,4-benzodithianes, the bromination is accomplished by Br- via an orbital-controlled vicarious nucleophilic substitution of hydrogen occurring on dibromodisulfonium ions (as 4).
