Regioselective α-addition of organocopper reagents to γ-(benzothiazole-2-thio)-α,β-enoates governed by anchimeric co-ordination. Synthesis of α-alkylated-β,γ-enoates
Abstract
The introduction of a leaving group, with co-ordination properties towards organocopper reagents, in the γ-position of α,β-enoates, changes the regioselectivity of the nucleophilic addition process leading to α-addition products.
