A new synthetic strategy for natural triquinanes is presented as a model study. Stereospecific rearrangement of the ready accessible bicyclo[3.3.1] nonanic acetoxychloride 6 gave the cis-pentalamic hydroxyaldehyde 5, which has been converted into the ketone 4 already reported as a key intermediate in some syntheses of the title capnellenes.
提出了一种新的天然三喹烷合成策略,作为模型研究。易获得的双环[3.3.1]壬酸乙酰氯6的立体特异性重排得到顺式-戊酰胺基羟醛5,该化合物已被转化为酮4,已被报道为标题capnellenes的某些合成中的关键中间体。
