Palladium catalyzed transfer hydrogenolysis of protected peptides using a recyclable polymer-supported formate as hydrogen donor affords pure hydrogenolyzed products without the need for any chromatographic purification steps and provides a facile method for the clean and efficient removal of some of the commonly used protecting groups in peptide synthesis. 相似文献

The synthesis of the first polymer-supported TADDOL is reported. Its efficiency as chiral ligand of Ti(IV) was studied in the Diels-Alder cycloaddition of cyclopentadiene to 3-crotonoyl-1,3-oxazolidin-2-one, and was superior to that observed for its homogeneous equivalent. (4R,5R)-α,α,α′,α′-2-pentaphenyl-4,5-dimethanol-1,3-dioxolane. Recycling of the heterogeneous Ti(IV)-TADDOLate was also studied, being the most suitable method for the repreparation of the catalyst from the ligand after use.
