Abstract

Analysis of published data on the Mannich reaction [1–5] shows that the problem whether well known precursors used in this reaction are suitable for acetylenes I is still unsolved [1– 5]. Until now there is no direct experimental evidence showing whether dialkylaminomethanols R'2NCH2OH (II) are the only feasible reactants or the same role can be played by esters III or formals IV. This controversy as to the structure of precursors for ...
