A radical cyclization strategy for the concise total synthesis of (±)-geissoschizine
摘要:
A short synthetic route to (+/-)-geissoschizine (1) was developed that features the construction of a Corynanthe-skeleton via radical cyclization of vinyl iodide, which was easily prepared by assembly of three fragments. New pentacyclic molecules formed by the radical cyclization were also reported. (C) 1997 Elsevier Science Ltd.
