✦ Synopsis

2-Amino-2-deoxy-D-glucose hydrochloride reacts with such /?-dicarbonyl compounds l-6 as 2,4_pentanedione

or ethylacetoacetate to give pyrroles 1 or 2 respectively. However, when 1 -phenyl-1,3-butanedione was used6, two products (5 or 6) could be obtained in the presence of triethylamine, formed through the keto-enamine intermediates 3 or 4, respectively. The product formed in 74% yield was tentatively formulated as 5.

It has been shown that sugars or amino sugars react with j?-dicarbonyl compounds in presence of dehydrating agents to give furan or pyrrole derivativeslm8. In the present work, 3-ethoxycarbonyl-5-(D-arabino-tetrahydroxybutyl)-2-methylfuran' (1) was boiled under reflux with hydrazine hydrate for one
