标题:Zn(Otf)2-Promoted Chemoselective Esterification Of Hydroxyl Group Bearing Carboxylic Acids
摘要:Selective Esterification Of Aliphatic And Aromatic Carboxylic Acids With Various Alcohols Is Studied Using Triphenylphosphine,I-2,And A Catalytic Amount Of Zn(Otf)(2). Use Of This Catalyst Allows The Formation Of Esters At A Faster Rate With Good To Excellent Yield By Activating The In Situ Generated Acyloxyphosphonium Ion Intermediate. During The Esterification Process,Both Their Aromatic And Aliphatic Hydroxyl Groups Are Fully Preserved From Trans-Esterification. The Results Show That The Bulkiness And The Reactivity Of This Doubly Activated Intermediate Iii Control The Selectivity And The Rate Of The Reaction,Respectively. The Method Is Also Useful For Direct Amidation Reactions.

权利人:LASSALLE LAURENT; YVERGNAUX FLORENT
摘要:The invention relates to the fields of fatty substance chemistry, specifically of the ceramide-type compound synthesis. The invention resides substantially in the synthesis of ceramide-type compounds. Specifically, the aim of the invention is a new enzymatic synthesis method, comprising at least one amidification step and one esterification step, achieved through lipases, among fatty acids and/or esters thereof and amino alcohols. The resulting ceramide-type compounds can be used as cosmetic and/or pharmaceutical compositions, in particular as dermatological compositions in conjunction or in admixture with one or more suitable cosmetic and/or pharmaceutical excipients or carriers. The method has an interest particularly in the synthesis of active compounds useful in the fields of cosmetology and/or pharmacology and specifically of dermatology.

标 题:Method of using laser induced injury to activate topical prodrugs
发明人：HERRON G S; BOMMANNAN D B
权利人:HERRON G S; BOMMANNAN D B
摘要:Methods and compositions are disclosed for improving the wound healing process and increasing collagen synthesis following laser induced thermal injury. The method comprises delivering prodrugs to a target site before the target site is injured and taking advantage of those enzymes that are physiologically-expressed to promote wound healing to convert the prodrugs to active drugs. The claimed invention has the advantage of the prodrugs being readily available to immediately participate in the wound healing process, but not have any negative side-effects of the active drug being present before injury occurs.

摘要:The present invention relates to a catalyst useful for polyurethane or polyisocyanurate synthesis comprising an aqueous and/or alcoholic solution of lithium chloride encapsulated in a (meth)acrylic copolymer capsule shell, wherein the (meth)acrylic copolymer capsule shell is obtained or obtainable by reacting: i) 10 to 90 weight-% of a first (meth)acrylate composition comprising a polyester of (meth)acrylic acid with a C2 to C24 alkylpolyol; ii) 90 to 10 weight-% of a second (meth)acrylate composition comprising a monoester of (meth)acrylic acid with a C1 to C24 alkanol; wherein the weight-% are based on an overall weight of all (meth)acrylates of 100 weight-%. In further aspects, the invention relates to a catalytic composition comprising the catalyst and an epoxide composition; a process for preparation of an aqueous and/or alcoholic solution of lithium chloride encapsulated in a (meth)acrylic copolymer capsule shell, and also to an aqueous and/or alcoholic solution of lithium chloride encapsulated in an acrylic copolymer capsule shell obtained or obtainable from the process, as well as to the use of the catalyst or of the aqueous and/or alcoholic solution of lithium chloride encapsulated in an acrylic copolymer capsule shell obtained or obtainable from the process for the preparation of polyurethane or polyisocyanurate. The invention also relates to a polyurethane or polyisocyanurate obtained or obtainable from the reaction of at least: a) a polyisocyanate composition; b) a polyol composition; in the presence of an epoxide composition and a catalyst comprising an aqueous and/or alcoholic solution of lithium chloride encapsulated in a (meth)acrylic copolymer capsule shell, wherein the (meth)acrylic copolymer capsule shell is obtained or obtainable by reacting: i) 10 to 90 weight-% of a first (meth)acrylate composition comprising a polyester of (meth)acrylic acid with a C2 to C24 alkylpolyol; ii) 90 to 10 weight-% of a second (meth)acrylate composition comprising a monoester of (meth)acrylic acid with a C1 to C24 alkanol; wherein the weight-% are based on an overall weight of all (meth)acrylates of 100 weight-%. Furthermore, the invention relates to a process for the preparation of the polyurethane or polyisocyanurate.
