One-pot multi-component synthesis and solid state structures of functionally rich polyether macrocycles

Densely functionalized polyether macrocycles can be prepared in one pot in yields up to 60% by the rhodium(II)-catalyzed decomposition of methyl diazoacetoacetate in the presence of a variety of substituted or unsaturated 5- and 6-membered ring cyclic ethers. A comprehensive analysis of the solid state conformations of the macrocyclic geometries is detailed as well as novel mechanistic insights about the multi-component condensation reaction. Copyright

Practical synthesis of chiral 2-morpholine: (4-Benzylmorpholin-2-(s)-yl)- (tetrahydropyran-4-yl) Methanone mesylate, a useful pharmaceutical intermediate

A commercial synthesis was developed for the production of (4-benzylmorpholin-2-(S)-yl)-(tetrahydropyran-4-yl) methanone mesylate, la, a key starting material for a phase 2, new investigational drug candidate at Eli Lilly and Company. The target compound was produced in the clinical pilot plant by the combination of two key steps: resolution of a morpholine amide intermediate to install the S-morpholino stereocenter in 35% yield and a high-yielding (89%) Grignard reaction to generate the title compound la, isolated as a mesylate salt. The Grignard reaction was found to proceed optimally when using a combination of I2 and DIBAL-H for the initiation. In addition, the Grignard reagent formation was monitored by ReactMax calorimetry, and proof-of-concept studies were completed, demonstrating that the Grignard step could potentially be run as a continuous process with magnesium recycling.

Photoinduced, Copper-Catalyzed Carbon-Carbon Bond Formation with Alkyl Electrophiles: Cyanation of Unactivated Secondary Alkyl Chlorides at Room Temperature

We have recently reported that, in the presence of light and a copper catalyst, nitrogen nucleophiles such as carbazoles and primary amides undergo C-N coupling with alkyl halides under mild conditions. In the present study, we establish that photoinduced, copper-catalyzed alkylation can also be applied to C-C bond formation, specifically, that the cyanation of unactivated secondary alkyl chlorides can be achieved at room temperature to afford nitriles, an important class of target molecules. Thus, in the presence of an inexpensive copper catalyst (CuI; no ligand coadditive) and a readily available light source (UVC compact fluorescent light bulb), a wide array of alkyl halides undergo cyanation in good yield. Our initial mechanistic studies are consistent with the hypothesis that an excited state of [Cu(CN)2]- may play a role, via single electron transfer, in this process. This investigation provides a rare example of a transition metal-catalyzed cyanation of an alkyl halide, as well as the first illustrations of photoinduced, copper-catalyzed alkylation with either a carbon nucleophile or a secondary alkyl chloride.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of 4-Chlorotetrahydropyran, you can also check out more blogs about1768-64-5
