摘要
A simple chemical oxidation of 2-deacetoxytaxinine J derivative 3 using an excess of dimethyldioxirane (DMDO) results in a highly regio- and stereospecific hydroxylation of the C-1 position to afford the 1 beta-hydroxy alpha-4(20)-epoxide 6 and 1 beta-hydroxy beta-4(20)-epoxide 7. A plausible mechanism of this reaction via 'insertion' is proposed. (C) 2000 Elsevier Science Ltd. All rights reserved.
