(EN) The new (Alpha)-alkyl-O-oxy-benzylamin derivatives, which have in the phenylic cycle as substituants one or at most two halogen atoms of a number in the periodic system from 17 to 53, the atom(s) of halogen being in the meta position with respect to the amino-alkyl rests, have salidiuretic and antihypertensive properties. They are obtained, for example, by chlorination, halogenation or iodization. (FR) Les nouveaux derives de l"(Alpha)-alcoyle-o-oxy-benzylamine, qui presentent dans le cycle phenylique comme substituants un ou au plus deux atomes d"halogene d"un nombre d"ordre dans le systeme periodique de 17 a 53, le ou les atomes d"halogene se trouvant en position meta par rapport au reste amino-alcoyle, possedent des proprietes salidiuretiques et antihypertensives. On les obtient par exemple par chloruration, bromuration ou ioduration.
Chiral Phosphoric Acid-Catalyzed Enantioselective Transfer Hydrogenation of <i>ortho</i>-Hydroxyaryl Alkyl N−H Ketimines
The first enantioselective chiral phosphoricacid-catalyzedtransferhydrogenation of unprotected ortho-hydroxyaryl alkyl N−H ketimines using Hantszch di-tert-butyl ester as a reductant is reported. A variety of ortho-hydroxybenzylamines were obtained in good to excellent yields and enantiomeric excesses.
