## Abstract Photocyclization reactions were carried out on 2โalkoxybenzophenones 1aโh and ethyl 2โbenzoylโphenoxyacetates 5aโe in three solvents of different polarity (benzene, acetonitrile and methanol) to examine solvent and substituent effects on the cyclization of 1,5โbiradical intermediates to
The regioselectivity of acylation of a range of 6-O-protected glycosides using Pseudomonas cepacia lipase in vinyl acetate was investigated. In general, cY-glycosides were acylated at the O-2 position and P-glycosides were acylated at the O-3 position. The effects of varying the size/hydrophobicity
