摘要:A Method Has Been Developed For The Methylation Of The C3' Amide Of Taxol C And Paclitaxel. Taxol C And Paclitaxel Were Sequentially Silylated At The 2',7,And 1-Hydroxyl Groups With Tert-Butyldimethylsilyl Chloride,Triethylsilyl Chloride,And Dimethylsilyl Chloride,Respectively. Subsequent Reaction With Potassium Tert-Butoxide And Methyl Iodide Provided The Corresponding N-Methylated Taxane Derivatives. Removal Of The Silyl Protecting Groups Furnished N-Methyltaxol C And N-Methylpaclitaxel.
