Phase-Transfer-Catalyzed Cyclopropanation. Synthesis of 1,2-Dibenzoyl-3-arylcyclopropanes

The 1,t-2,t and 1,t-2,c-isomers of 1,2-dibenzoyl-3-phenylcyclopropanes have been prepared by the cycloaddition of carbonyl-stabilized sulfur ylides to trans-chalcones under phase-transfer conditions.The configurations of the isomers were characterized by

Studies on Carbonyl Stabilized Sulphonium Ylids : Reaction with α,β-Unsaturated Carbonyl Compounds

1,2,3-Trisubstituted-cyclopropanes (3a-j) have been prepared by the reaction of the sulphur ylids phenacylidenedimethylsulphurane (1a) and 4-methylphenacylidenedimethylsulphurane (1b) with α,β-unsaturated ketones (2).The carbonyl stabilized ?-sulphuranes (1) have been generated from their corresponding salts.Structural assignments of the products are based on their IR and PMR data.
