Stereochemistry and kinetics of amines addition to acetylenic esters

The reactions of a series of methyl para-substituted phenylpropiolates 1a-e with piperidine, morpholine, and diethylamine in methanol and dimethylformamide (DMF) have been studied and their rates measured.The products were methyl β-(N,N-dialkylamino)-p-substituted cinnamates 2-4a-e. 1H NMR spectra were used to determine the configuration of the products.The ρ values in methanol ranged between 0.34 and 1.24 whereas in DMF they were between 0.85 and 1.88.The values of ΔS(excit.) favor a bimolecular rate-limiting step mechanism.
