Abstract
The synthesis, NMR structure determination, and molecular modelling of the conformationally restricted diastereomeric sugar azido acids 1 and 2 are presented. The bicyclic structures of these compounds are obtained through a iodocyclization reaction on the C-allyl glycoside of the D-arabinofuranose. Cyclic tetrapeptide 11 containing the amino acid derived from 1 linked to the RGD sequence has been synthesized; this compound was found to be a selective antagonist of αvβ3 integrins expressed on GM 7373 cells
