合成路线1
该中间体在本合成路线中的序号：(II)Paclitaxel (I) is selectively protected at the side-chain hydroxyl group with 2,2,2-trichloroethyl chloroformate in pyridine to afford the carbonate ester (II). Subsequent acylation of (II) with 3-methyl-3-[(2,4,6-trimethoxybenzyl)thio]butyric acid (III) provides ester (IV). Removal of the trimethoxybenzyl protecting group of (IV) by means of formic acid in the presence of L-cysteine gives rise to thiol (V).
