analysis. The reactions with methanol gave only one isomer (7–9). The reaction of 1 with water afforded both boron epimers (50/50 ratio). The reaction of 2 with water observed at −50° showed both B-epimers in 80/20 ratio, whereas the same reaction with 3 gave only one isomer. In all cases the main isomer has the N-methyl trans to the C-methyl group and the B-phenyl cis to the N-methyl group. The X-ray

Several representative oxazaborolidines have been synthesized and evaluated against S. mutans for antibacterial activity. This is the first reported antibacterial activity of this class of compounds. The minimal inhibitory concentration values ranged from 0.53 to 6.75 mM.
