摘要

Although biomimetic polyene cyclizations [1] have been honed into powerful tools for complex molecule construction in the half-century since the pioneering efforts of Stork and Eschenmoser,[2] several limitations remain. For instance, while nature can deploy heme-or vanadium-based enzymes [3] to enantioselectively fashion an array of natural products, such as 1–3 (Scheme 1),[4] from a broad range of appropriate precursors, such as 4–6,[5] ...
