An oxyma derivative, (2,2-dimethyl-1,3-dioxolan-4-yl)methyl 2-cyano-2-(hydroxyimino)acetate, displayed a remarkable effect on selective esterifications of primary alcohols. A wide range of carboxylic acids could be esterified with primary alcohols by using EDCI, NaHCO3 in 5% H2O-CH3CN. The Oxyma derivative can be removed after the reaction via a simple basic or an acidic aqueous workup procedure.
