A synthetic strategy was developed for the preparation of α-ethynyl-α,β-epoxy-β-formyl- and α-ethynyl-α,β-epoxy-β-(hydroxymethyl)cyclohexanone from cyclohexenone as a model study in a proposed synthesis of escobarines. This highly functionalized ring is found in the anti-TB cassane-type diterpenes escobarines A and B. Introduction of the β-hydroxymethyl group was carried out by reversing the chemical
开发了一种合成策略,用于从环己烯酮制备 α-乙炔基-α,β-环氧-β-甲酰基-和 α-乙炔基-α,β-环氧-β-(羟甲基)环己酮,作为拟议合成中的模型研究escobarines。这种高度官能化的环存在于抗结核 cassane 型二萜 escobarines A 和 B 中。 β-羟甲基的引入是通过使用磺酰基的阴离子和多聚甲醛的亲电攻击逆转烯酮的化学反应性来进行的. β-(羟甲基)环己烯酮的进一步官能化提供了所需的化合物。
