Synthesis of α-<scp>d</scp>-Idoseptanosyl Glycosides Using an <i>S</i>-Phenyl Septanoside Donor

Abstract

[reaction: see text] An S-phenyl alpha-D-idoseptanoside donor was used in the selective preparation of a series of alpha-D-idoseptanosyl glycosides. Glycosylation of a methyl beta-D-glycero-D-guloseptanoside acceptor with the new donor constituted the first synthesis of a septanose disaccharide.
