longstanding challenge posed by the complex diterpene vinigrol has been answered for the first time. The notorious difficulty in synthesizing vinigrol stems from its unprecedented decahydro-1,5-butanonaphthalene ring system, eight contiguous stereocenters, and highly congested functionality. This Communication delineates a stereocontrolled 23-step route to vinigrol that is scalable (>5 g prepared of a late-stage
复杂的二萜乙烯醇所带来的长期挑战首次得到了解答。合成长春醇的困难源于其前所未有的十氢-1,5-丁萘环系统、八个连续的立体中心和高度拥挤的官能团。该通讯描述了一种立体控制的 23 步合成维尼醇的路线,该路线可扩展(> 5 g 后期中间体制备),对保护基化学的依赖程度最低,并通过许多独特的化学选择性转化来促进。
