REGIOSELECTIVE REDUCTION OF α, γ-ONOCERADIENEDIONE : SYNTHESIS OF LANSIOLIC ACID

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.
