Abstract : Aluminum isopropoxide in normal fashion reduces the carbonyl of trans- but not of cis-alpha-phenylchalcone; lithium aluminum hydride reduces the carbonyls of both, and also the carbonyl of alpha, beta-diphenylchalcone. Phenyllithium adds 48% 1,2 and 33% 1,4 to the trans isomer but chiefly 1,4 to the cis; and it adds only 1,2 to the carbonyl of alpha-beta-diphenylchalcone. These results are
摘要: 异丙醇铝以正常方式还原反式-α-苯基查尔酮的羰基,但不还原顺式-α-苯基查尔酮的羰基;氢化铝锂还原两者的羰基,也还原 α, β-二苯基查尔酮的羰基。苯基锂向反式异构体添加 48% 1,2 和 33% 1,4,但主要向顺式异构体添加 1,4;它仅在 α-β-二苯基查尔酮的羰基上增加 1,2。这些结果显示符合一致的模式。(作者)
