Kinetic studies of conjugate addition of amines to allenic and acrylic esters and their correlation with antibacterial activities against Staphylococcus aureus
allenic and acrylicesters in conjugateadditionreactions with various amines were investigated. Competition experiments showed that amines reacted selectively with allenic esters, which was also confirmed by quantitative determination of the rate constants. The antibacterial activity against Staphylococcus aureus of allenic and acrylicester derivatives were also determined. Allenic esters were found
