Syntheses of (+/-)-axamide-1 (2) and (+/-)-axisonitrile-1 (1) are described. The syntheses require 12 steps and 13 steps, respectively, from vinylogous ester 8 and feature the diastereoselective cyclization of unsaturated ester 7 to perhydroindan 5. Some interesting reactions of the organometallic derived from [(trimethylsilyl)methyl]magnesium chloride and cerium trichloride are also described.
描述了(+/-)-ax酰胺-1(2)和(+/-)-轴腈-1(1)的合成。合成需要分别从乙烯基酯8到12步和13步,并且具有不饱和酯7到非氢茚满5的非对映选择性环化的特点。还描述了一些有趣的有机金属化合物的反应,这些有机金属化合物来自[[(三甲基甲硅烷基)甲基]氯化镁和三氯化铈。 。
