Part-B: Cyclopropanation from Chiral ylide with  unsaturated carbonyl: The simple ylide reaction is feasible in most of the  unsaturated carbonyl substrate, but need to synthesize chiral derived  unsaturated carbonyl substrates as well as the different ylides for any changes to be made on cyclopropane ring. There are few reported methods where chiral sulfur ylide is used for cyclopropanation, but still need a convenient method. Herein we report cyclopropanation formation on reaction of chiral auxiliary having sulfur ylide with -unsaturated carbonyls. it is useful particularly where chiral auxiliary with  unsaturated carbonyl substituted substrates and -substituted yllide synthesis is not possible.
