Reaktionsschritte

A mixture of 5.7 g (38.4 mmole) of D-xylose of mp. 153° C. and 6.9 g (38.4 mmole) of D-glucose of mp. 143° C. is heated to approximately 80° C. with 52.7 g (176.8 mmole) of BEPDIB. The readily volatile constituents are then removed in vacuo (10-3Torr). Subsequent distillation gives 7.3 g of bp. 78° C./10-3Torr in addition to 11 g of yellowish residue.
