SmI3 mediated reginospecific Michael addition of ω-bromo-acetophenone to α,β-unsaturated alkynones

Abstract
SmI3 mediated regiospecific Michael addition of ω-bromo-acetophenone to α,β-unsaturated alkynones was investigated. A new method for the synthesis of 1,5-dicarbonyl compounds was put forward. This reaction suffers from the influence of solvents seriously.
