Oxetane δ-amino acids: Chemoenzymatic synthesis of 2,4-anhydro-5-N-(t-butoxycarbonyl)amino-D-lyxonic acid

Starting from 1,2-O-isopropylidene-D-xylose, methyl 2,4-anhydro-3,5-di-O- benzyl-D-lyxonate (4) was synthesized. Debenzylation and transformation of the primary hydroxyl group yielded methyl 2,4-anhydro-5- N-(t-butoxycarbonyl)amino- D-lyxonate (9). While

Ring contraction reactions of 2-O-methanesulfonates of α-hydroxy-γ-lactones in aqueous medium to oxetane-2-carboxylic acids: A convenient synthesis of 3'-O-methyloxyetanocin and a formal synthesis of oxetanocin

Barton decarboxylative rearrangement of thiohydroxamic ester 17 directly provided the key oxetanosylthiopyridyl glycosides 18 which were successfully coupled to N-benzoyladenine. A two-step ring contraction of the tosylate 7 to the oxetane-2-carboxamide 2
