Abstract

Microwave-Assisted Construction of C-Hydroxydiketopiperazines Using Lanthanum(III) Triflate. -A highly efficient and convenient method for the construction of C-hydroxydiketopiperazines is developed using Lanthanum(III) triflate as a recyclable reagent. Microwave heating dramatically enhances the reaction rate without the epimerization of the existing chiral center in the substrate. -(WANG, Q.-P.; ZHANG, H.-B.; NING, X.; HANG, H.; HUANG, Z.-L.; SONG, H.-R.; WANG, X.; WANG*, P.
