BIOTRANSFORMATION OF 2α,5α,10β,14β-TETRA-ACETOXY-4(20),11-TAXADIENE BY THE FUNGUS CUNNINGHAMELLA ECHINULATA
摘要:
2α,5α,10β,14β-Tetra-acetoxy-4(20),11-laxadiene (1) could be regioselectively transfonned into 6α,10β-dihydroxy-2α,5α,14β-triacetoxy-4(20),11-taxadiene (2) by Cunninghamella echinulata in fair yield.6β,10β-Dihydroxy-2α,5α,14β-triacetoxy-4(20),11-taxadiene (3).10β-bydroxy-2α,5α,14β- triacetoxy-4(20),11-taxadiene (4),10β-hydroxy-4β,20-epoxy-2α,5α,14β-triacetoxy-tax-11-ene (5) as minor products were also isolated.
