Reagent-Dependent Regioselective Control in Multiple Carbohydrate Esterifications

摘要

Regioselective control in organotin-mediated multiple acy-lation of carbohydrates is presented. The acylation reagent could be efficiently used to direct the product formation. Reagent-dependent thermodynamic and kinetic control and dynamic assistance mechanisms are suggested, resulting in the efficient preparation of building blocks that normally require many steps with traditional synthesis.
