Amphidinolide B: Asymmetric Synthesis of a C7−C20 Synthon
摘要:
An asymmetric synthesis of a C-7-C-20 synthon of amphidinolide B is described. The synthesis entails the construction of C-7-C-13 and C-14-C-20 fragments and makes extensive use of catalytic asymmetric bond constructions to establish the requisite stereochemical relationships. Fragment coupling proceeds by Suzuki cross-coupling and installs the trisubstituted diene unit that is among amphidinolide B's defining structural features.
