Designing new chiral hydroxamic acid ligands for the asymmetric epoxidation reaction in water
Abstract: Herein, we report the synthesis of new chiral hydroxamic acid ligands for the V-catalysed asymmetric epoxidation reaction in aqueous solution. During the course of this project, a wide range of allylic alcohols were epoxidised under mild reaction conditions. The target epoxides were …

Synthesis of new chiral pyrylium salts, the corresponding phosphinine and pyridine derivatives and the kinetic studies of the epimerization of pyrylium salts.
… as precursors to many heteroaromatic systems, chiral pyrylium salts are almost unknown in the literature. One reason for this scarcity is that pyrylium salts are often involved as intermediates rather than as isolated and characterized materials. Another is that many pyrylium salts preparations …
