1.We have synthesized a series of cis- and trans-1,1-phthaloyl-2-phenyl-3-(p-alkyl-benzoyl)cyclopropanes and established their configurations.2.We have suggested a method for preparing trans-1,1-phthaloyl-2-phenyl-3-(p-alkyl-benzoyl)cyclopropanes by acid isomerization of the cis isomers in CF3COOH.3.The ionic hydrogenation of cis-1,1-phthaloyl-2-phenyl-3-(p-alkylbenzoyl)cyclopropanes involves reduction of benzoyl to benzyl and opening of the three-membered ring to form 1,1-phthaloyl-2-phenyl-3-(p-alkylbenzyl)-2-propenes, whereas in the ionic hydrogenation of the trans isomer benzoyl is again reduced to benzyl but the three-membered ring is preserved, forming 1,1-phthaloyl-2-phenyl-3-(p-alkylbenzyl)cyclopropanes. |
