Penta-O-actyl-l,2-dideoxy-l-nitro-D-gluco-hept-l-enitol reacts with methyl acetoacetate in an unusual Michael reaction, giving the normal adduct (6), and a bicyclic derivative (9) that arises from quasi-dimerization of the former when a high concentration of the base is used.

3,4,5,6,7-Penta-O-acetyl-l,2-dideoxy-l-nitro-D-gluco-and -D-g&cto-hept-lenitol and 3,4,5,6-tetra-O-acetyl-l,2-dideoxy-l-nitro-D-xylo-hex-l-enitol react with 3-aminocrotonic esters, yielding mixtures of the epimeric Michael adducts. These are thermally stable, and do not cyclize to pyrroles. The stru
