标题:Dehydration Reactions In Water. Brønsted Acid−surfactant-Combined Catalyst For Ester,Ether,Thioether,And Dithioacetal Formation In Water
摘要:Dehydration Reactions In Water Have Been Realized By A Surfactant-Type Catalyst,Dodecylbenzenesulfonic Acid (Dbsa). These Reactions Include Dehydrative Esterification,Etherification,Thioetherification,And Dithioacetalization. In These Reactions,Dbsa And Substrates Form Emulsion Droplets Whose Interior Is Hydrophobic Enough To Exclude Water Molecules Generated During The Reactions. Detailed Studies On The Esterification Revealed That The Yields Of Esters Were Affected By Temperature,Amounts Of Dbsa Used,And The Substrates. Esters Were Obtained In High Yields For Highly Hydrophobic Substrates. On The Basis Of The Difference In Hydrophobicity Of The Substrates,Unique Selective Esterification And Etherification In Water Were Attained. Furthermore,Chemospecific,Three-Component Reactions Under Dbsa-Catalyzed Conditions Were Also Found To Proceed Smoothly. This Work Not Only May Lead To Environmentally Benign Systems But Also Will Provide A New Aspect Of Organic Chemistry In Water.

权利人:NIMNI MARCEL; HAN BO
摘要:A composition for application to the skin can stimulate the in vivo synthesis of collagen and proteoglycans and improve the appearance of the skin, increasing its elasticity and fullness. In general, a composition according to the present invention comprises: (1) an antioxidant compound in a quantity sufficient to enhance collagen synthesis in the skin; (2) an organic penetrant in which the antioxidant compound is soluble in a sufficient quantity that a concentration of the antioxidant compound sufficient to enhance collagen synthesis can be applied topically and penetrate the skin; (3) a mixture of essential amino acids; (4) a supplemental source of sulfur; and (5) a topical pharmaceutically acceptable carrier. The antioxidant compound can be lipoic acid, a lipoic acid analogue or derivative, a bioflavonoid, a constituent of ginkgo, or an isoflavone. The organic penetrant is preferably benzyl alcohol. Other ingredients, such as esters of tocopherol and ascorbic acid, can be included.
