Abstract
2-Cyano-3,3-bis(methylthio)acrylonitrile was treated with 6-amino-6-deoxy-1,2:3,4-di- O-isopropylidene-α- d-galactopyranose, 6-amino-6-deoxy- d-galactose diethyl dithioacetal, and 6-amino-6-deoxy-2,3:4,5-di- O-isopropylidene- d-galactose diethyl dithioacetal to give the corresponding 6-deoxy-6-(2,2-dicyano-1-methylthiovinylamino)- d-galactose derivatives. 6-Deoxy-6-(2,2-dicyano-1-methylthiovinylamino)- d-galactose diethyl dithioacetal yielded 6-amino-6-deoxy-5- O,6- N-(2,2-dicyanovinylidene)- d-galactose diethyl dithioacetal. On heating with bases, 6-deoxy-6-(2,2-dicyano-1-methylthioacrylamido)- d-galactose afforded a mixture of two comounds.
