Abstract
6''-alpha-Maltosyl-maltotriose and 6''-alpha-D-glucosyl-maltotriose were prepared from Novamyl degradation of 6-O-alpha-maltosyl-alpha-cyclodextrin and 6-O-alpha-D-glucosyl-alpha-cyclodextrin, respectively. NMR spectroscopy was used to elucidate their structural identities, in a combination of COSY experiments. Further, a mechanism for the degradation was proposed based on the Novamyl active site geometry.
