Synthesis of α-bromoisolevoglucosenone and its cyclopenta annulation

4,4-Dimethyl-3-nitro-10,11-dioxatricyclo[6.2.1.02,6]undec-5-en-7-one possessing a bicyclic iridoid skeleton was synthesized in two steps from isolevoglucosenone which was obtained in turn from levoglucosenone through 4-benzyloxy-2-tosyloxy deri

AZIDO DERIVATIVES OF 1,6-ANHYDRO-β-D-HEXOPYRANOSES CORESPONDING TO 3-DEOXY- AND 4-DEOXY-D-GLUCOSAMINE

Nucleophilic substitution of the tosyloxy group in 1,6-anhydro-3-deoxy-2-O-p-toluenesulfonyl-β-D-arabino-hehxopyranose(II) with lithium azide gave azido derivate V wich was acetolysed and deacetylated to 2-azido-2,3-dideoxy-D-ribo-hexose(XI).The oxirane r
