Microbial Transformation of Isoprenoid Systems By Means of Zoophthora (erynia) Ovispora (nowakowski) Batko

Epoxidation of double bond was the main reaction performed by Zoophthora (Erynia) ovispora on methyl and ethyl alpha-campholenyl ketones 1 and 6. Apart from epoxides 2, 3, 7, and 8, some other products were isolated, with additional oxygen function in alpha-position to the double bond (9 and 10). The presence of the BAEYER-VILLIGER reaction product (4) and diketone 11 is also postulated
