The synthesis of [l-(2-pyridylthio)alkyl]boronic esters was explored as a means of determining the diastereoisomeric purity and the absolute configuration of the carbon 0( to the boron of the corresponding 1-chloroalkyl derivatives. The significant nonequivalences observed in the 1H NMR spectra of t
