The synthesis, in racemic form, of the insect juvenile hormone inhibitor brevioxime (1) is described, as well as exploratory studies that led to the related model compounds 14 and 15a. The route to 1 involves Ag(+)-mediated coupling of the amine derived from 20 with the beta-keto thioester 32. Acid treatment of the coupled product 33 led by acetal hydrolysis, cyclization, and desilylation to 34a,b
描述了昆虫幼体激素抑制剂brevioxime(1)的外消旋形式合成,以及探索性研究导致了相关模型化合物14和15a的合成。通往1的途径涉及Ag(+)介导的20衍生的胺与β-酮硫酯32的偶联。偶联产物33的酸处理由乙缩醛水解,环化和去甲硅烷基化作用生成34a,b,从中得到1通过氧化并转化为肟达到目的。在氨基组分20的合成中,已知但不寻常的还原用于将腈转化为胺盐酸盐。
