The Oxidation of Acetals by Ozone
Autor: Claude Moreau, Alain Malaval, Daniel Frehel, Paul Atlani, Pierre Deslongchamps
Publikováno v: Canadian Journal of Chemistry. 52:3651-3664
Ozone reacts very smoothly with acetals to give the corresponding esters. There are six gauche conformations that are theoretically possible for an acetal function. It is shown that only three of them are reactive toward ozone. It is proposed that a

The Importance of Conformation of the Tetrahedral Intermediate in the Hydrolysis of Amides. Selective Cleavage of the Tetrahedral Intermediate Controlled by Orbital Orientation
Autor: Daniel Fréhel, Alain Malaval, Paul Atlani, Pierre Deslongchamps
Publikováno v: Canadian Journal of Chemistry. 51:1665-1669
The basic hydrolysis of N-disubstituted imidate salts proceeds via a hemi-orthoamide tetrahedral intermediate which can in principle give amide–alcohol or ester–amine products. Experimental evidence has been obtained which shows that the specific

The Importance of Conformation of the Tetrahedral Intermediate in the Hydrolysis of Esters. Selective Cleavage of the Tetrahedral Intermediate Controlled by Orbital Orientation
Autor: Pierre Deslongchamps, Paul Atlani, Daniel Fréhel, Alain Malaval
Publikováno v: Canadian Journal of Chemistry. 50:3405-3408
The hydrolysis or the transesterification of esters proceeds via a hemi-orthoester tetrahedral intermediate. There are nine different gauche conformers possible for such a tetrahedral intermediate and it is proposed that each of them should decompose
