Abstract

When 2-aminoisoquinoline-1,3-(2H,4H)-dione (1a) or 2-phenylisoquinoline-1,3-(2H,4H)-dione (1b) was reacted with some of the aromatic aldehydes, derivatives 2a-e and 3a-e respectively were obtained in moderate yield (55%-60%).
On the other hand, when compounds 1a, b stirred overnight with aldo-sugars either hexoses or pentoses in a pyridine/pepperdine mixture, new glycosides 4a-e and 5a-e respectively were produced.
