Synthesis and absolute stereochemistry of (-)-protolichesterinic acid, antitumor antibiotic lactone from Cetraria islandica
摘要:
The first synthesis of (-)-protolichesterinic acid is described. The approach, based on a facially selective 2 + 2 cycloaddition reaction of dichloroketene with an enantiopure O-alkyl enol ether, permits the assignment of the absolute stereochemistry of the natural product to be made (2S,3R).
