[{"from": "human", "value": "Synthesize a molecule that matches the given characteristics. The molecule is an amino disaccharide consisting of alpha-L-threo-hex-4-enopyranuronic acid and 2-acetamido-2-deoxy-alpha-D-glucopyranose residues joined in sequence by a (1->4) glycosidic bond. It is an amino disaccharide, a member of acetamides, an alpha,beta-unsaturated monocarboxylic acid, an enol, a glucosamine oligosaccharide and a glycosylglucose derivative. It is functionally related to a 4,5-dehydro-D-glucuronic acid and a N-acetyl-alpha-D-glucosamine."}, {"from": "gpt", "value": "[C][C][=Branch1][C][=O][N][C@@H1][C@H1][Branch2][Ring2][Branch2][C@@H1][Branch1][O][C@H1][Branch1][=Branch1][O][C@@H1][Ring1][=Branch1][O][C][O][O][C@H1][C@@H1][Branch2][Ring1][Ring2][C@H1][Branch1][S][C][=Branch1][N][=C][Branch1][Ring2][O][Ring1][=Branch1][C][=Branch1][C][=O][O][O][O][O][O]"}]
