摘要

Abstract Functional zinc reagents can be applied to palladium catalyzed cross-coupling reaction with (2 E, 4 E)-and (2 E, 4 Z)-5-bromopenta-2, 4-dienal. The corresponding functional dienic aldehydes were obtained in goods yields. From the (2 E, 4 E) isomer, the (2 E, 4 E) dienals were isolated as single isomer according to a total stereoselective reaction. But, from the (2 E, 4 Z) isomer the coupling reaction has lead to a mixture of (2 E, 4 E) and ...
