An efficient asymmetric synthesis of allo- and pseudo-7,8-dimethoxyberbane systems through tin-mediated three component coupling
摘要:
Three component coupling reactions of chiral 3-substituted 6,7-dimethoxy-3,4-dihydroisoquinoline with allylic tin reagents and unsaturated acid chlorides followed by intramolecular Diels-Alder reactions afford allo- and pseudo-7,8-dimethoxyberbane systems in high diastereomeric excess.
