参考标题:Diazepinium Perchlorate: A Neutral Catalyst For Mild, Solvent-Free Acetylation Of Carbohydrates And Other Substances 作者:Santosh Kumar Giri,Rajesh Gour,K. P. Ravindranathan Kartha 摘要:Protecting Groups Such As Tbdms/tbdps/tr Ethers And Isopropylidene/benzylidene Acetals Present On A Substrate Unaffected. Regioselective Hydroxyl Protection In Partially Protected Carbohydrate Derivatives/polyhydroxylic Compounds Was Possible And Was Proved To Be A Convenient Time-Saving Alternative To The Conventional Synthesis Of Such Compounds. Easy Preparation Of The Catalyst, Mild Reaction Conditions
