METHOD FOR OBTAINING OF OXIDIZED DERIVATIDES OF 3-/1,1- DIMETHJLHEPTJL/-6,6A,7,8,10,10A- HEXAHJDRO- 1- XJDROHJ- 6,6- DIMETHJL- 9H- DIBENZO/B,D- PJRANES

摘要

1-Hydroxy-9-keto-3-alkyl-dibenzo[b,d]pyrans or 1,9-dihydroxy-3-alkyl-dibenzo[b,d]pyrans are oxygenated on the penultimate carbon of the alkyl side chain by fermentation with a strain of the micro-organism Bacillus cereus.
