HOT MELT EXTRUDED SOLID DISPERSIONS CONTAINING A BCL2 INHIBITOR

A pro-apoptotic solid dispersion comprises, a Bcl -2 family protein inhibitory compound of Formula A as defined herein, dispersed in a solid matrix that comprises (a) a pharmaceutically acceptable water-soluble polymeric carrier, and (b) a pharmaceutically acceptable surfactant. A process for preparing such a solid dispersion comprises subjecting to elevated temperature the compound of Formula A, the water-soluble polymeric carrier, and the surfactant to provide an extrudable semi-solid mixture; extruding the semi-solid mixture; and cooling the resulting extrudate to provide a solid matrix comprising the polymeric carrier, and the surfactant and having the compound dispersed in essentially non-crystalline form therein. The solid dispersion is suitable for oral administration to a subject in need thereof for treatment of a disease characterized by overexpression of one or more anti-apoptotic Bcl -2 family proteins, for example cancer or an immune or autoimmune disease.

Fe-Catalyzed Anaerobic Mukaiyama-Type Hydration of Alkenes using Nitroarenes

Hydration of alkenes using first row transition metals (Fe, Co, Mn) under oxygen atmosphere (Mukaiyama-type hydration) is highly practical for alkene functionalization in complex synthesis. Different hydration protocols have been developed, however, control of the stereoselectivity remains a challenge. Herein, highly diastereoselective Fe-catalyzed anaerobic Markovnikov-selective hydration of alkenes using nitroarenes as oxygenation reagents is reported. The nitro moiety is not well explored in radical chemistry and nitroarenes are known to suppress free radical processes. Our findings show the potential of cheap nitroarenes as oxygen donors in radical transformations. Secondary and tertiary alcohols were prepared with excellent Markovnikov-selectivity. The method features large functional group tolerance and is also applicable for late-stage chemical functionalization. The anaerobic protocol outperforms existing hydration methodology in terms of reaction efficiency and selectivity.

Interrupting the Barton?McCombie reaction: Aqueous deoxygenative trifluoromethylation of o-alkyl thiocarbonates

The site-selective trifluoromethylation of aliphatic systems remains an important challenge. This work describes a light-driven, copper-mediated trifluoromethylation of O-alkyl thiocarbonates. The reaction provides broad functional group tolerance (e.g., alkyne, alkene, phenol, free alcohol, electron-rich and -deficient arenes), thereby offering orthogonality and practicality for trifluoromethylation. A radical organometallic mechanism is proposed.

Also disclosed is a method for treatinga neoplastic disease, an autoimmune disease, or a neorodegenerative disease with these compounds.

Ring opening of cyclic N,O-acetals with allyltrimethylsilane under Lewis acidic conditions

Five and six-membered cyclic N,O-acetals with N-carboxyalkyl and sulfonyl groups undergo clean and high yielding ring opening with allyltrimethylsilane in the presence of strong Lewis acids to give homoallylic amine derivatives.
