Enantioselective syntheses of decursinol angelate and decursin
摘要:
The practical enantioselective syntheses of decursinol angelate and decursin were achieved in eight steps from resorcinol. The stereochemistry was addressed using the catalytic asymmetric epoxidation of 7-acetoxy-2,2-dimethylchromene by chiral (salen)Mn complexes as the key step. (C) 2001 Elsevier Science Ltd.
