Oxovanadium(V)-induced diastereoselective oxidative homocoupling of boron enolates.
Oxovanadium(v)-induced dl-selective oxidative coupling of (Z)-boron enolate was demonstrated to give the corresponding 2,3-disubstituted 1,4-diketone in a good yield. High selectivity (up to 94 : 6) was attained when the reaction was performed with VO(OPr-i)2Cl at -30 °C.
