  • Smoking compositions containing an .alpha.-alkylcinnamaldehyde-release additive
    Patent number: 5301693
    Abstract: This invention provides smoking compositions which contain a novel .beta.-hydroxycarboxylate flavorant-release additive. Under cigarette smoking conditions, a combustible filler and/or paper wrapper additive such as calcium bis(2,2-diethyl-3-hydroxy-4-phenylmethylenedecanoate) pyrolyzes and releases .alpha.-hexylcinnamaldehyde as a volatile flavorant component of the cigarette smoke.

  • Preparation of oxycarboxylic acids
    Patent number: 4612391
    Abstract: 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.

  • Azetidine compounds and process for production
    Patent number: 4163855
    Abstract: 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.

  • Azetidine compounds and process for production
    Patent number: 4163856
    Abstract: 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.
