Abstract
PURPOSE: To prepare the titled compound useful as an antibacterial agent, by reacting an α-aminobenzylpenicillin with a benzoyl isocyanate or a benzoylcarbamic acid halide.
CONSTITUTION: The titled compound of formula IV (R11 is lower alkyl; R2 is H or OH; R3 are 2W3 lower alkanoyloxy groups, at least two of which are adjacent) can be prepared by reacting a compound of formula I or its reactive derivative with a compound of formula II or formula III (X is halogen) in a solvent such as dichloromethane at -30W35°C, pref. -10W20°C. The compound of formula IV thus prepared is an excellent antibacterial agent easpecially effective to the bacteria belonging to Pseudomonas genus.
