DOI: 10.1016/j.tet.2018.04.087
Abstract: Abstract Optically active cyclopropane derivatives were prepared by a novel, simple and green approach in high enantioselectivities using monosaccharide-based chiral crown ethers as phase transfer catalysts. The crown ethers having d -glucopyranoside, d -mannopyranoside and… read more here.

DOI: 10.1021/acscatal.3c00075
Abstract: 2-Aminobiphenyl palladacycles are among the most successful precatalysts for Pd-catalyzed cross-coupling reactions, including aryl amination. However, the role of NH-carbazole, a byproduct of precatalyst activation, remains poorly understood. Herein, the mechanism of the aryl amination… read more here.
