An organocatalytic enantioselective synthesis of the title compounds has been achieved. The stereogenic centers were generated by the iterative use of proline catalyzed α-aminoxylations and HWE olefination of aldehydes while the lactone ring was constructed by ring closing metathesis.
已经实现了标题化合物的有机催化对映选择性合成。通过重复使用脯氨酸催化醛的α-氨氧基化和HWE烯化来生成立体异构中心,同时通过闭环易位构建内酯环。
