AN EFFICIENT METHOD FOR THE PREPARATION OF HOMOALLYLIC ALCOHOL DERIVATIVES BY THE REACTION OF ALLYL IODIDE WITH CARBONYL COMPOUNDS IN THE PRESENCE OF STANNOUS HALIDE
Allyl iodide reacts in situ under mild conditions with stannous halide to form allyltin dihaloiodide, which in turn reacts with carbonyl compounds in an aprotic solvent to give the corresponding ho...
The synthesis of cyclic alkenylboronic half acids from vinyl and propenyl boronic esters and homoallylic alcohols by ring-closing metathesis is reported. The method is compatible with both conventional and microwave heating and comparable yields are obtained under both conditions. The cyclic alkenylboronicacids participate in Suzuki−Miyaura coupling reactions in good yields.
