โœฆ Synopsis

Iodonium ylides of methyl 3-oxo-trans,trans-6,8-tetradecadienoate (1) and diprotected methyl 3,5-di(tbutyldimethyl-silyloxy)-2,6,8-tetradecalrieneoate (5) undergo regio-and stereoselective inwamolecular cyclopropanation with Cu(I)CI catalysis to form key bicyclo[3.1.0] intermediates for prostaglandin synthesis.
