Botryodiplodia malorum

Methyl-5-hepten-2-one is a valuable precursor for microbial epoxidations and hence the production of chiral ethers with high optical purities. The biotransformation of 6-methyl-5-hepten-2-one (33) by Botryodiplodia malorum CBS 13450 to (/ )-sulcatol (84) was described [61], which is then epoxidised to the (55)-epoxide (85) and opened intramolecularly to cis-(2R,5R)-2-(2 -hydroxyisopropyl)-5-methyltetra-hydrofuran (86) and c/s-(35,67 )-3-hydroxy-2,2,6-trimethyltetrahydropyran (87). Reduction of 6-methyl-5-hepten-2-one (33) with baker s yeast to (5)-sulcatol (88) which was used as substrate for Kloeckera corticis... [Pg.143]

Other fungi used for the introduction of 7/ -hydroxy groups in steroids include Acremonium sp.155 and Botryodiplodia malorum 156,1 57. [Pg.386]
