A new route for semisynthetic docetaxel, 1, is described using 2-monosubstituted-4-phenyl-1,3-oxazolidine-5-carboxylic acids in esterification of 7,10-O-diTroc-10-desacetylbaccatin III (4). Subsequent deprotection of esters 10(+10′) afforded title compound 1 without removal of the Boc group.
一种半合成多西他赛的新路线1被描述为在7,10-O-diTroc-10-desacetylbaccatin III(4)的酯化反应中使用2-单取代的4-苯基-1,3-恶唑烷-5-羧酸。随后酯10(+10 ')的脱保护得到标题化合物1,而没有除去Boc基团。
