A new backbone model for a chiral carbohydrate-derived ketone for asymmetric epoxidation is presented. The oxo function is sited in a seven-membered ring fused to the sugar moety. The synthesized compound is an effective chirality-
Chlorambucilamide derivatives involving chiral glycosyl glycerols derived from D-glucosamine were synthesized in good yield by coupling the chlorambucil moiety to the amino group of omega-amino-(omega-1)-hydroxyalkyl 2-acylamino-4,6-O-benzylidene-2-deoxy-beta-D-glucopyranosides, and subsequent hydrolysis of the benzylidene group. The starting material was easily available from 2-acetamido-2-deoxy-D-glucose. The bonding of 2,3,4,6-tetra-O-pivaloyl-beta-D-galactopyranosylamine to chlorambucil by formation of an amide function is also described.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
