摘要：

A series of twelve 1,1-diphenylboroxazolidones (1b-12b) prepared from alpha-aminoacids and diphenylborinic acid were studied using one- and, in some cases, two-dimensional (HETCOR) NMR techniques. Interpretation of these spectra led to definitive assignment of all carbon, hydrogen, and boron resonances.
