[reaction: see text] A novel synthetic path to a potential intermediate for the synthesis of pseudomonic acid B was established by employing enantioselective deprotonation of a meso-cycloheptanone derivative bearing hydroxy groups at the 3,4,5,6-positions with lithium (S,S')-alpha,alpha'-dimethyldibenzylamide as a key step.
[反应:见正文]通过使用在3,4,5,6-位带有羟基的中环环庚酮衍生物的对映选择性去质子化,用锂( S,S')-α,α'-二甲基二苄基酰胺是关键步骤。
