Iron-promoted 1,5-substitution (SN2′′) reactions of enyne acetates and oxiranes with Grignard reagents
Acetate derivatives of 2-en-4-yne alcohols 1 and enyne oxiranes 4 regioselectively underwent 1,5-substitution (SN2′′) reactions with Grignard reagents in the presence of an iron compound to provide vinylallenes exclusively ...
Rhodium-catalysed alkoxycarbonylative cyclisation reactions of 1,6-enynes
(Wiley-VCH Verlag, 2011-04)
The rhodium-catalysed carbonylation of 1,6-enynes possessing an electron-deficient alkenyl moiety in an alcohol reagent in the presence of a rhodium complex proceeded stereo- and chemoselectively to afford exocyclic α,β-enoates.
Synthesis of α,β-unsaturated ketones by rhodium-catalyzed carbonylative arylation of internal alkynes with arylboronic acids
(Georg Thieme Verlag, 2008-10)
The Rh-catalyzed reaction of arylboronic acids with internal alkynes under a CO atmosphere in the presence of an acid additive afforded α,β-unsaturated ketones as the major products. Hydroacylation of internal alkynes, ...
