Research has been conducted on the biotransformation Of (8S,9R)-isocaryolan-9-ol (4a) and (1S,2S,5R,8S)-8-methylene-1,4,4-trimethyltricyclo [6.2.1.0(2'5)] uridecan-12-ol (5a) by the fungal phytopathogen Botrytis cinerea. The biotransformation of compound 4a yielded compounds 6-9, while the biotransformation of compound 5a yielded compounds 10-13. The activity of compounds 4a and 5a against B. cinerea has been evaluated. (8R,9R)- Isocaryolane-8,9-diol (6), a major metabolite of compound 4a, shows activity compared to its parent compound 4a, which is inactive. The effect of isocaryolanes 3,4a, and 5a, together with. their biotransformation products 6-8, 10, and 14-17, on the germination and radicle and shoot growth of Lactuca sativa (lettuce) has also been determined. Compounds 7-13 are, described for the first time.
