Geranylacetone and geranyloxycoumarin (aurapten) were investigated with 14 selected microorganisms for ω-hydroxylation and epoxydation of the subterminal double bond. Trichoderma koningii and Verticillium theobromae are in principal useable for both

While biotransformations of nortricyclanol did not give detectable products, microbial hydroxylation could be achieved by using its benzoate ester or its phenylcarbamate. Here eight fungi were found to hydroxylate these substrates in moderate yield.

Two novel microbial steroid hydroxylations were found in a screening of 131 microorganisms under aerobic conditions. 17 alpha-Hydroxyprogesterone was hydroxylated in the 8 beta-position by Corynespora melonis CBS 16260, and fermentation of 17 alpha-a

Biotransformations of several structurally related cinchona alkaloids were investigated, mimicking mammalian metabolism. Quinine was oxidized to the 1-N-oxide and 1′-N-oxide by Microsporum gypseum, whereas Cunninghamella echinulata yielded the know

A very efficient phase transfer reaction for the preparation of the homochiral substituted cyclopentenones 13, 15 and 17 from (R)-4-acetoxycyclopent-2-enone 1 in a chirality transfer process is reported. The synthetic applications of the reaction pro

A new method was developed to obtain lactones from butterfat. The application of lipases and capillary gas-liquid chromatography with chiral phases for the separation of γ-lactone enantiomers resulted in elucidation of the racemic composition of γ-

Lipases are enzymes of interest in different disciplines in natural science: medicine, biochemistry, biology, the food industry, and in recent years, organic chemistry. Although the type of enzyme is the same with respect to different aims, lipases a
