    摘要: This invention provides a process for the conversion of an alicyclic .alpha.,.beta.-olefinically unsaturated ketone compound to an acyclic oxocarboxylic acid product which contains at least one less carbon atom per molecule than the ketone starting material.The conversion involves ozonation of the alicyclic .alpha.,.beta.-olefinically unsaturated ketone in an aqueous alcohol reaction medium, followed by a heating step.

    摘要: Novel azetidine, and particularly 3-pyridyl-azetidine, compounds are disclosed. These compounds are produced from .gamma.-amino alcohols by a sequence comprising disulfonation to produce the sulfonamido-alkylsulfonate and then cyclization to the N-sulfonylazetidine. These azetidine compounds may then be transformed, as desired, to various N-derivatives by substitution of hydrogen or other univalent organic groups on the secondary amine of the azetidine ring.

    摘要: Novel azetidine, and particularly 2-pyridyl-azetidine, compounds are disclosed. These compounds are produced from amino-esters by a sequence comprising conversion to the sulfonamide, reduction of the ester to the alcohol, sulfonation of the resultant alcohol and cylization to the N-sulfonylazetidine. This azetidine compound may then be transformed, as desired, to various N-derivatives by substitution of hydrogen or other univalent organic groups on the secondary amine of the azetidine ring.
