Abstract
Methods have been developed for the generation and trapping of dithiol ane-isocyanate imminium methylides which are a new type of azomethine methylide-derived 1,3-dipole. These species add efficiently and stereo selectively to electron deficient olefins yielding novel dithiolane-pr otected gamma-lactans which can be efficiently deprotected to yield to corresponding lactam systems.
