Besseau, Francois published the artcileHydrogen-bond basicity of esters, lactones and carbonates, Product Details of C7H13NO2, the publication is Journal of the Chemical Society, Perkin Transactions 2: Physical Organic Chemistry (1972-1999) (1994), 485-9, database is CAplus.
A thermodn. hydrogen-bond-basicity scale pKHB (logarithm of the formation constant of 4-fluorophenol-base complexes in CCl4) has been determined for esters, lactones and carbonates, and correlated to a spectroscopic basicity scale. In the esters R1CO2R2 the hydrogen-bond basicity is decreased by bulky alkyl R1 substituents (steric effect) but increased by branched and lengthened alkyl R2 substituents (electronic effects). Quant. structure-basicity relationships have been established in the XCO2Et (X varying from CF3 to Me2N) and XC6H4CO2Et (X varying from 4-NO2 to 4-Me2N) series. Vinylol. strongly increases hydrogen-bond basicity: Me2NCH:CHCO2Et is the most basic ester presently known. Cyclization increases the hydrogen-bond basicity of esters and carbonates.
