Abstract

Préparation de dérivés de 5,6-dihydro-2-méthyl-1,4-oxathiine. On prépare d'abord des sulfoxydes (cis, trans ou mélange des deux) de 1,3-oxathiolane et on les traite catalytiquement en milieu acide avec ouverture du noyau pour parvenu au composé désiré moyennant perte d'eau. Applications chimiques générales.Preparation of 5,6-dihydro-2-methyl-1,4-oxathiine derivatives. Sulphoxides (cis, trans or mixture of the two) of 1,3-oxathiolane are first prepared and they are treated catalytically in an acidic medium with opening of the nucleus to obtain the desired compound with loss of water. General chemical applications.
