Synthesis of l-Octaarginine through Microencapsulated Palladium-Catalyzed Allyl Ester Deprotection
摘要:
Octaarginine has been described as a molecular transporter. We report a useful synthesis of orthogonally protected L-octaarginine by using a method based on a microencapsulated palladium catalyst. Known palladium-based methods for allyl ester deprotection have been modified to facilitate purification of the unprotected intermediates. This improvement in the purification step has also been tested with a variety of allyl alpha-amino esters and allyl alpha,beta-unsaturated esters.
