Popis: | Dithiolane-isocyanate imminium methylides which are a new type of azomethine methylide-derived 1,3-dipole undergo efficient and regioselective cycloaddition to conjugated carbonyls and thiocarbonyls to yield predominantly 1,3-oxazolidine- and thiazolidine-2-thiones formed from the initial cycloadducts via loss of thiirane. |
