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
