Jm. Urbanczyk et al., MICROBIAL TRANSFORMATION OF ISOPRENOID SYSTEMS BY MEANS OF ZOOPHTHORA(ERYNIA) OVISPORA (NOWAKOWSKI) BATKO, Journal of basic microbiology, 33(2), 1993, pp. 141-146
Epoxidation of double bond was the main reaction performed by Zoophtho
ra (Erynia) ovispora on methyl and ethyl alpha-campholenyl ketones 1 a
nd 6. Apart from epoxides 2, 3, 7, and 8, some other products were iso
lated, 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.
