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.
