摘要：
Chloroformylation of 5,5-dimethyl-1,2-oxathiolan-4-one 2,2-dioxide 4 with Vilsmeier reagent (DMF/POCl3) led to the formation of cyclic beta-chlorovinylaldehyde (4-chloro-5,5-dimethyl-3-formyl-1,2-oxathiolene 2,2-dioxide 5). Compound 5 reacted with formamidine, o-aminophenol, 1,2-phenylenediamine, aminopyrazole, and aminotetrazole to give the corresponding heterocyclic compounds. (c) 2005 Wiley Periodicals, Inc.
