Regioselective reduction of .ALPHA.,.GAMMA.-onoceradienedione : Synthesis of lansiolic acid.
摘要:
Synthesis of lansiolic acid is completed through the regioselective reduction of α, γ-onoceradienedione as a key step, and this unique regioselectivity is discussed based on the conformation analysis of 3-keto-4, 4, 10-trimethyldecalin system.
