Ester and nitrile derivatives of (2-alkylidene)malonic acids, obtained by the condensation of (i-PrO)3Ti derivatives of CH2(CO2Et)2, CH2(CN)CO2Et, and CH2(CN)2 with α,β-unsaturated aldehydes, react with NaBH4 and RMgX to give esters and nitriles of the corresponding allylmalonic acids.These reactions are accompanied by complete retention of the geometry of the residual double bonds.The reaction of diethyl (2-alkenylidene)malonates with PhCO3H leads to the selective formation of monoepoxides and does not affect the α,β-double bond.
