We present an efficient, simple, metal- and solvent-free silica-gel-promoted synthesis of functionalized conjugated dienes by sequential aza-Michael/Michael reactions by starting from commercially available primary amines and propiolic esters. The scope a

An improved procedure of esterification of propynoic acid, based on the N,N'-dicyclohexylcarbodiimide 4-dimethylaminopyridine condensation, is presented, which gives good results with primary, secondary, allylic and homoallylic alcohols.Reactions conditions are mild.Some limitations are given.
