摘要

Ytterbium metal promoted reaction of chalcone with equimolar amount of benzaldehyde gave 2-benzoyl-5-phenylhydroxymethyl-1, 3, 4-triphenylcyclopentanol, whereas 2, 5-bis (benzoyl) cyclopentanol was obtained by the reaction with excess amount of the aldehyde. In addition, similar reaction of 3-anisyl-1-phenyl-2-propen-1-one with anisaldehyde afforded 2: 2 adduct, 5-[anisyl (anisylmethoxy) methyl] cyclopentanol, irrespective of amount of the ...
