The synthesis of 3-spirohydantoin derivatives of D-allose and D-ribose is reported. The key step is the stereoselective conversion of glyco-alpha -aminonitriles from ulose derivatives of D-glucose and D-xylose using titanium(IV) isopropoxide as a mild and efficient catalyst. Cyclisation of the glyco-alpha -aminonitriles give the target spirohydantoins. (C) 2001 Elsevier Science Ltd. All rights reserved.

Anomeric spirohydantoin derivatives from monosaccharides are known for various biological properties. We describe herein the synthesis of the 3-spirohydantoin derivatives of D-allose and D-ribose. The key step is the stereoselective glyco-alpha-aminonitrile formation from ulose derivatives of D-glucose and D-xylose using titanium tetra-isopropoxide as a mild and efficient catalyst.
