You could be based in a university, combining chemical research with teaching; in a pharmaceutical company, working on developing and trialing new drugs, helping to ensure national healthcare provision keeps pace with new discoveries , SDS of cas: 103-47-9, 103-47-9, Name is N-Cyclohexyltaurine, molecular formula is C8H17NO3S, belongs to thiazines compound. In a document, author is Hladikova, Veronika, introduce the new discover.
NEW SYNTHETIC APPROACH LEADING TO 1-OR 1,3-DISUBSTITUTED 2-THIOURACIL-5-CARBOXYLATES VIA DIMROTH REARRANGEMENT OF ISOMERIC THIAZINES
Methyl 1-substituted and 1,3-disubstituted-2-thiouracil-5-carboxylates (3b-d) were prepared using new synthetic approach involving base-catalyzed cyclization of easily available S-[3-methoxy-2-(methoxycarbonyl)-3-oxoprop-1-en-1-yl]isothiuronium salts (1a-d) to methyl 2-substituted imino-4-oxo-3,4-dihydro-2H-1,3-thiazine-5-carboxylates (2a-d) and their nucleophile-assisted Dimroth rearrangement to methyl 1-substituted and 1,3-disubstituted-2-thiouracil-5-carboxylates (3b-d). Cyclization step is very sensitive towards the base used – e.g. 1a react with stronger bases or bases in excess to give bis-[3-methoxy-2-(methoxycarbonyl)-3-oxoprop-1-en-1-yl] sulfide (4) as the only isolated product.
