Glucosyl dienes 1 have been reacted with the achiral 2H-azirine 4 and with glyoxylates, forming fused structures of type 5 and disaccharide-like compounds 7 with good to excellent selectivity. Glucosyl dienes 1 participated as dienophiles in reactions with Schiffbasesderivedfromanilines forming isoquinolines 10 and 11. The diastereoselectivity of this reaction is poor.
