The synthesis of the C-28 through C-38 segment of the marine natural product okadaic acid was accomplished employing a highly enantio- and diasteroselective aldol condensation reaction of a chiral vinylogous urethane enolate. The stereocenter at C-29 was addressed utilizing a diastereoselective hydroboration reaction.
海洋天然产物冈田酸的C-28至C-38段的合成是通过手性乙烯基类氨基甲酸酯烯醇酸酯的高度对映体和非对映体选择性羟醛缩合反应完成的。利用非对映选择性的硼氢化反应解决了C-29的立体中心。
