easily prepared from sorbaldimine throught deprotonation with LDA in THF at −60°C and subsequent trapping of the organo lithium intermediate by trimethylsilylchloride. The condensation of this new organosilicon reagent with several aldehydes, in the presence of catalytic CsF in DMSO at 100°C leads directly, after the hydrolysis of the imine function, to the expected trienals in good yields and with excellent
摘要 6-三甲基甲硅烷基N-叔丁基山梨醛亚胺可以通过山梨醛亚胺在-60℃的THF中用LDA去质子化,然后用三甲基甲硅烷基氯化物捕获有机锂中间体而容易地制备。这种新的有机硅试剂与几种醛的缩合,在 DMSO 中的催化 CsF 存在下,在 100°C 下,在亚胺官能团水解后,直接产生预期的三烯醛,收率良好,具有优异的 E 选择性。
