    • The present invention is directed to processes for the synthesis of morphinans. In particular, a process for cyclizing a β,γ-bicyclic ketone compound to form a nordihydrothebainone product using the Grewe cyclization reaction is improved by forming a reaction mixture comprising a β,γ-bicyclic ketone compound, a cyclizing acid and a water scavenging cyclization additive. In one embodiment, the Grewe transformation occurs in the presence of an acid anhydride as the cyclization additive. Further, the present invention is directed to processes for converting α,β-bicyclic ketone compounds (e.g., by-products of the Grewe cyclization reaction) to β,γ-bicyclic ketone compounds, wherein the β,γ-bicyclic ketone compounds may be recovered to further undergo Grewe cyclization and form the nordihydrothebainone product.
    • 本发明涉及合成吗啡喃的方法。 特别地,通过形成包含γ-双环酮化合物,环化酸和水的反应混合物,使Gewe环化反应使γ-二环酮化合物环化以形成一种二氢苯乙酮产物的方法得到改善 清除环化添加剂。 在一个实施方案中,Grewe转化发生在作为环化添加剂的酸酐的存在下。 此外,本发明涉及将α,bb-二环酮化合物(例如,Grewe环化反应的副产物)转化为γ-双环酮化合物的方法,其中γ-双环酮 可以回收化合物以进一步进行Grewe环化并形成去氢二苯酮产物。

    • An organized mobile multicomponent conjugate (OMMC) and method of using to enhance binding of weakly binding compounds to a target. A lamellar structure containing at least two binding compounds is assembled under conditions in which the binding compounds self-regulate in or on the lamellar structure, forming a cooperative ensemble that is capable of binding with enhanced affinity to a complementary affinity site on a target. Each binding compound is bound to the lamellar surface, and may be connected by a linker. The OMMC may contain an effector molecule, such as a diagnostic or therapeutic agent, for administration to a patent who is then diagnosed or treated using the effector molecule.

    • An improved process is disclosed for preparing aromatic fluorides by diazotization-fluorination in hydrogen fluoride wherein the diazotized reaction mixture includes an oxidizing agent such as nitrosonium ion from excess diazotization agent. The improvement includes, prior to decomposing the diazonium fluoride, adding to the diazotized reaction mixture a member selected from hydrazine, aromatic hydrazine, semi-carbazide, thio-semicarbazide, acid salts thereof, sulfur dioxide, sodium sulfate, and sodium bisulfite to remove at least a portion of the oxidizing agent. Urea was found to be ineffective.
