Application of Cycloaddition Reactions to the Syntheses of Novel Boron Compounds

Abstract

This review covers the application of cycloaddition reactions in forming the boron-containing compounds such as symmetric star-shaped boron-enriched dendritic molecules, nano-structured boron materials and aromatic boronic esters. The resulting boron compounds are potentially important reagents for both materials science and medical applications such as in boron neutron capture therapy (BNCT) in cancer treatment and as drug delivery agents and synthetic intermediates for carbon-carbon cross-coupling reactions. In addition, the use of boron cage compounds in a number of cycloaddition reactions to synthesize unique aromatic species will be reviewed briefly.

Dendritic Structures Functionalized with Boron Clusters, in Particular Carboranes, and Their Biological Properties

“…Carboranes display a rich chemistry, at the level of the C−H groups, but also in some cases at the level of B−H groups. The chemistry of carboranes has been reviewed [ 7 , 8 ], in particular with emphasis on their biological properties [ 9 ]. Indeed, the large number of boron atoms present in these boron clusters made them desirable instruments for cancer treatment using boron neutron capture therapy (BNCT).…”
