合成路线1
该中间体在本合成路线中的序号：(XVII)The synthesis of tritium-labeled taxol [13-3H]-taxol (b) has been described: The oxidation of baccatin III (I) with MnO2 in chloroform gives 13-oxobaccatin III (XV), which is silylated with chlorotriethylsilane in pyridine yielding 13-oxo-7-O-(triethylsilyl)baccatin III (XVI). The reduction of (XVI) with tritiated borane (prepared from tritiated sodium borohydride and BF3) in THF affords [13-3H]-7-O-(triethylsilyl)baccatin III (XVII), which is condensed with (3S-cis)-1-benzoyl-4-phenyl-3-(trimethylsilyloxy)azetidin-2-one (XVIII) by means of butyllithium in THF to give [13-3H]-2',7-bis-O-(triethylsilyl)taxol (XIX). Finally, this compound is deprotected with 48% HF and pyridine in THF.
