| 摘 要： | a, a'-Dibenzylidenecycloalkanones are very important intermediates for synthesis of bioactive pyrimidine derivatives1. Usually, their preparation is achieved by the cross-aldol condensation, which has low yield and too many by-products2. The methods with catalyst such as RuCl33a, TiCl3 (SO3CF3)3b, InCl34H2O3c or BMPTO d require expensive catalysts and long reaction times and give more by-products. Acetals have been successfully applied as a protective group in organic synthesis4, and…
