Studies on the total synthesis of the saponaceolides. 1. Enantioselective synthesis of the spiroketal subunit
摘要:
An asymmetric synthesis of the tricyclic spiroketal subunit of the saponaceolides is described in which the absolute stereochemistry at C-2' and C-6' is established through a conformationally and stereoelectronically controlled cyclization of a dihydroxyketone pyran Intermediate.
