HOT: Practical utility of silyl-protected dioxaborinanes in rhodium-catalysed 1,4-addition reactions

This Hot Article by Christopher Frost et al. at the University of Bath (UK) describes the utility of novel silyl-protected dioxaborinanes, performing as excellent donors in rhodium-catalysed 1,4-addition reactions under anhydrous conditions. This approach allows the enantioselective addition to arylidene Meldrum’s acid derivatives and a subsequent asymmetric synthesis of 4-arylchroman-2-ones, an important class of bioactive and pharmaceutically-relevant compounds.
