Formation of reagent-selective products from 2-(4,5-dihydrothi- azol-2-ylthio)-1-arylethanone with different nucleophiles
摘要:
The reactions of 2-(4,5-dihydrothiazol-2-ylthio)-1-arylethanone with different nucleophiles including semicarbazide hydrochloride, hydroxylamine hydrochloride, hydrazine, ethylenediamine and aminoethanol have been investigated, and the formation of a variety of products with different reagents is highlighted.[GRAPHICS].

A series of new heterocyclic β-ketosulfides was prepared by the reaction of the corresponding heterocyclic thiols with α-bromoacetophenone and its derivatives. Oxidation of the products using m-CPBA gave the corresponding heterocyclic β-ketosulfones, which, on treatment with Selectfluor™ under anhydrous condition underwent electrophilic fluorination resulting in new heterocycles with difluoromethylene
