Boronic Esters in Stereodirected Synthesis

Publisher Summary This chapter explores that the influence of boron chemistry on various areas of research in inorganic, organic, and theoretical chemistry is well documented. In fact, many models currently employed to describe chemical bonding in general can be traced to attempts to understand bonding in boranes. The confirmation of many theoretical predictions in boron chemistry relies on direct and indirect structural information provided by various physical methods that fortunately became available almost at the same rate as that with which the interest in boron compounds was growing. It discusses that developments in boron chemistry have been greatly accelerated by nuclear magnetic resonance (NMR). 11 B NMR has been at the centre of interest from the beginning accompanied by routine 1 H NMR measurements: and occasional 14 N, 19 F and 31 P NMR work. The availability of “multinuclear” facilities for PFT NMR spectrometers stimulates the measurement of the NMR spectra of other nuclei, like 29 Si, l19 Sn or other metals, to obtain additional information. The chapter not only summarizes the experimental facts required for obtaining the maximum information from NMR studies on boron compounds but also attempts to incorporate new NMR parameters into the known data set.

Nuclear Magnetic Resonance Spectroscopy of Boron Compounds Containing Two-, Three- and Four-Coordinate Boron

Arylboration of vinylarenes and methyl crotonate with aryl halides and bis(pinacolato)diboron by cooperative Pd/Cu catalysis has been developed, giving 2-boryl-1,1-diarylethanes and an α-aryl-β-boryl ester in a regioselective manner. The reaction is compatible with a variety of functionalities and amenable to be scaled-up to a gram scale with no detriment to the yield. A short synthesis of the biologically active compound CDP840 was performed using the present reaction as a key step.
