摘要:Polyether (meth)acrylates based on cyanuric acid or substituted cyanuric acid and multifunctional alcohol, which optionally include triethanolamine units, have wide applications in UV curable adhesives, coatings, inks, sealants, paints or 3D printing. These polyether acrylates have rigid cyanurate structure endowing the material with extra strength and thermal stability. Furthermore, triethanolamine unit, when present, endows the material with anti-oxygen inhibition property in UV curing process. These polyether (meth)acrylates have low viscosity and high reactivity towards UV curing. The cured resins have high resilience and strength. The process of making the polyether (meth)acrylates includes the synthesis of trifunctional polyether polyols through controlled polymerization of propylene oxide using multifunctional alcohol (such as glycerol and sucrose), cyanuric acid or substituted cyanuric acid, and optionally triethanolamine, in the presence of a catalyst, followed by the synthesis of polyether (meth)acrylates through transesterification or through direct esterification of the trifunctional polyether polyols.

摘要:The present disclosure is directed to a process for the synthesis of chenodeoxychloic acid, 25-hydroxycholesterol and 1α,25-dihydroxycholesterol from 17-keto steroids. A cholic acid side chain is stereospecifically introduced by reaction of the appropriate 17-keto steroid with ethyltriphenylphosphonium halides to produce the 17-ethylidene derivative which is allowed to react with acrylic acid esters or propiolic acid esters followed by hydrogenation.

摘要:Families of antagonist-agonists and opiate narcotics are produced from norhydrocodeinone. In a preferred embodiment, norhydrocodeinone is refluxed with sulfosalicyclic dimethylketal and delta-6-enol ether derivatives and is then converted entirely to the ether by the addition of dry tetrahydrofuran simultaneously with the removal of the thus produced ether. The ether is then reacted with methanesulfonic acid and N-bromoacetamide to form the hydrobromide salt of the 7-bromodimethylketal derivative. From this derivative, a variety of products can be derived, including the novel further intermediate 14 hydroxynorcodeinone. The present invention enables derivation using a starting material which, unlike the starting materials of prior art processes, is available in the natural (-) or synthetic (+) form. Thus, the method of the present invention provides the only known route for the synthesis of (+) forms of various derivatives and intermediates, such as (+)-7-bromo-dimethylketal nordihydrocodeinone.
