Toward the Second Generation Synthesis of Aplyronine A: Stereocontrolled Assembly of the C1−C19 Segment by Using an Asymmetric Nozaki−Hiyama−Kishi Coupling
摘要:
An efficient synthesis of the C1-C19 segment of aplyronine A is described. Stereoselective construction of the C14-C15 (E)-trisubstituted double bond and the C13 stereocenter was achieved by using an asymmetric Nozaki-Hiyama-Kishi coupling.

A stereoselective synthesis of a C1–C18 segment of the structure of the cytotoxic macrolides amphidinolides G and H is reported. The target compound was retrosynthetically disconnected into three fragments. In the synthetic sense, connection of the fragments was made by means of a Stille coupling and a Julia–Kocienski olefination. Precursors from the chiral pool were used as the starting materials
