—— | 1-(4-methoxyphenyl)-4-(1,1-dimethylethyl)-2,3-azetidinedione | 298710-66-4 | C14H17NO3 | 247.294 |
Baker's yeast (Saccharomyces cerevisiae) reductions were applied to the synthesis of the paclitaxel C-13 side-chain analogue. An easily synthesized alpha-keto-beta-lactam (1-(4-methoxyphenyl)-4-tert-butylazetidin-2,3-dione, 4) was reduced by yeast cells to give a mixture of enantiomerically pure cis and trans isomers. Both compounds were isolated and characterized, and their absolute configurations were confirmed by X-ray crystallographic analysis.Key words: Taxol®, C-13 side-chain, paclitaxel analogues, optically pure alpha-hydroxy-beta-lactams, baker's yeast-catalyzed reductions.
