Abstract The Michael-addition reactions of levoglucosenone with diethyl malonate, ethyl cyanoacetate, 2-nitropropane, and 2-methylcyclohexanone have been examined, using a variety of catalysts. This reaction may be conveniently used to prepare, in reasonable yields, 4-substituted levoglucosenone derivatives having the d - erythro configuration. Better yields of the diethyl malonate adduct were obtained
