The first synthetic advances towards the novel diterpenoid tonantzitlolone 1 are described. The key steps in the synthesis involve a chromium(II) Reformatsky reaction, a diastereoselective C1 extension and an expeditious aldol coupling step of two advanced precursors.
描述了向新颖的二萜类坦西隆1的第一个合成进展。合成中的关键步骤涉及铬(II)Reformatsky反应,非对映选择性C 1延伸和两个高级前体的快速羟醛偶联步骤。
