FORMATION OF STABLE CYCLOADDUCTS IN REACTIONS OF BENZOTHIAZOLIUM N-PHENACYLIDE WITH METHYLENECYCLOPROPENES

Article abstract of DOI:10.1246/cl.1981.1493

Benzothiazolium N-phenacylide adds to the cyclic double bond of methylenecyclopropenes having no acyl group on the 4-position to give stable <3+2> cycloadducts.This is the first example for the formation of stable <3+2> cycloadducts in the reaction of 1,3
