4-allyl-2-methylene-1,3-oxathiolan-5-ones through the 1,5-cyclization of a thiocarbonyl ylide intermediate followed by Claisen rearrangement with allene episulfide through the 1,3-cyclization of the intermediate. Other alkenyl and alkynyl diazoacetates also gave similar products through the thiocarbonyl ylide without affording its intramolecular 1,3-dipolar cycloadduct.
