A Model Route Toward the Synthesis of Conformationally Constrained Polyhydroxylated Dipeptides from Natural Carbohydrates

Enantiopure 6,7-diacetoxy-3-t-butoxycarbonylaminoazabicyclo[3.3.0]octan-2- one-8-carboxylic acid 14 (pyrrolizidinone amino acid) was synthesized in 14 steps and 5.8% overall yield from tri-O-benzyl-D-arabinose 5 through the formyl C-imino-sugar 9 as a key
