Abstract
Dithiolane- isocyanate imminium methylides which are a new type of azo methine methylide-derived 1,3-dipole undergo efficient and regioselect ive cycloaddition to conjugated carbonyls and thiocarbonyls to yield p redominantly 1,3-oxazolidine- and thiazolidine-2-thiones formed from t he initial cycloadducts via loss of thurane.
