Reinvestigation of the iodocyclization of 4,5,7-tri-O-benzyl-3-(N-benzylacetamido)-1,2,3-trideoxy-D-gluco-hept-1- enitol: Unexpected formation of a 1,3-imino-heptitol derivative

The NIS-mediated iodocyclization of 4,5,7-tri-O-benzyl-3-(N-benzylacetamido)-1,2,3-trideoxy-D-gluco-hept-1-enitol gave unexpectedly a 1,3-imino-heptitol derivative, namely 2-O-acetyl-N-benzyl-4,5,7-tri-O-benzyl-1,3-dideoxy-1,3-imino-D-glycero-D- ido-heptitol. This compound is a new example of a rare class of azetidine imino alditol derivatives which have interesting properties such as glycosidase inhibitors. The physical and spectral data for this imino heptitol were essentially identical to those reported for 2,6-anhydro-4,5,7-tri-O-benzyl-3-(N-benzylacetamido)-3-deoxy-D-glycero-D- ido-heptitol, a derivative of C-(2-acetamido-2-deoxy-α-D-glucopyranosyl)methanol obtained from the same precursor [Lay, L.; Nicotra, F.; Panza, L.; Verani, A. Gazz. Chim. Ital. 1992, 122, 345-348]; these findings cast doubts on the structure reported for the latter product.
