Chemical engineers work across a number of sectors, processes differ within each of these areas, but chemistry and chemical engineering roles are found throughout, creation and manufacturing process of chemical products and materials.5872-08-2, Name is (7,7-Dimethyl-2-oxobicyclo[2.2.1]heptan-1-yl)methanesulfonic acid, belongs to thiazines compound, is a common compound. In a pantent, author is Trinh, Trieu N., once mentioned the new application about 5872-08-2, Safety of (7,7-Dimethyl-2-oxobicyclo[2.2.1]heptan-1-yl)methanesulfonic acid.
A multicomponent access to 1,3-thiazine-6-phenylimino-5-carboxylates
The multicomponent reaction of ethyl 3-aminocrotonate (1), substituted phenylisothiocyanates (2a-i) and acetic anhydride (7), afforded facile access to a series of substituted 1,3-thiazine-6-phenylimino-5-carboxylates under mild conditions in 15-65% yields. Limited tolerance for modification of the anhydride moiety was noted with a significant reduction in yield for propionic and trifluoroacetic anhydrides. The use of benzoic anhydride favoured a two-component coupling product. (C) 2016 Elsevier Ltd. All rights reserved.
