Despite the potential of alpha-fluoroethers in medicinal chemistry, their synthetic methods, especially etherification of aliphatic alcohols, have been limited. Herein, we developed two- and three-step gem-difluoropropargylation of aliphatic alcohols including amino acid derivatives and naturally occurring bioactive molecules. Highly chemoselective etherification proceeded by using the gem-difluoropropargyl bromide dicobalt complex in the presence of silver triflate and triethylamine. Decomplexation of dicobalt complexes was achieved by using cerium ammonium nitrate or N,N,N?-trimethylethylenediamine. The thus obtained gem-difluoropropargyl ethers were converted to various alpha-difluoroethers which are expected to be useful for medicinal chemistry.

In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 503614-92-4, name is 1-(4-Methoxyphenyl)-7-oxo-6-(4-(2-oxopiperidin-1-yl)phenyl)-4,5,6,7-tetrahydro-1H-pyrazolo[3,4-c]pyridine-3-carboxylic acid, introducing its new discovery.

Apixaban is a novel anticoagulant drug acting as a direct, selective and reversible inhibitor of the coagulation factor Xa. Forced degradation under stress conditions were carried out in order to establish its stability profile. The drug was shown to be stable under photolytic, thermolytic and oxidative conditions, while under hydrolytic conditions, up to seven degradation products were generated for about 15% of drug degradation. The degradation products have been detected by linear gradient reversed phase high-performance liquid chromatography coupled with a photo diode array and with electrospray ionization tandem mass spectrometry. A combination of multistage mass spectrometry and high-resolution mass spectrometry (HR-MS) allowed the structural elucidation. The product ions of the degradation products were compared to those of the apixaban protonated ion so as to assign the most structures possible. This required a study in depth of the drug’s fragmentation pattern, which has not been reported so far. In view of the products formed, it appears that hydrolysis of the oxopiperidine moiety of apixaban occurred in acidic medium, whereas that of the tetrahydro-oxo-pyridine moiety would further happen under alkaline conditions. Asides from characterization, the LC method was shown to indicate stability and validated as per the criteria described by the ICH guidelines.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Efficient intramolecular hydroamination/cyclization of primary and secondary conjugated aminodienes can be effected by using organolanthanide precatalysts of the type Cp-2LnCH(TMS)2 (Cp- = eta5-Me5C5; Ln = La, Sm, Y; TMS = SiMe3) and CGCSmN(TMS)2 (CGC = Me2Si(eta5-Me4C5)(tBuN)). The transformation proceeds cleanly (? 90% conversion) at 25-60 C with good rates and high regioselectivities, and with electronic effects leading to significant rate enhancements. Some features of the reaction parallel monosubstituted aminoalkene hydroamination/cyclization, including rate law (zero order in [aminodiene]), and rate enhancements observed with larger lanthanide ionic radii and/or more open catalyst ligation structures. Good to excellent diastereoselectivity is obtained in the synthesis of 2,5-trans-disubstituted pyrrolidines (80% de) and 2,6-cis-disubstituted piperidines (99% de) with using the corresponding alpha-methyl aminodiene precursors. Formation of 2-(prop-1-enyl)piperidine with the chiral C1-symmetric precatalyst (S)-Me2Si(OHF)(CpR*)SmN(TMS)2 (OHF = eta5-octahydrofluorenyl; Cp = eta5-C5H3; R* = (-)-menthyl) proceeds with up to 69% ee.

A transition metal-free, regioselective C-5 trifluoromethylation of 2,3-dihydropyridin-4(1H)- ones (cyclic enaminones) with trimethyl(trifluoromethyl) silane (TMSCF3) was developed that proceeds under mild conditions at room temperature. This direct transformation was successful with both electron-rich and electron-deficient cyclic enamin- ACHTUNGTRENUNGones. This method bypasses substrate prefunctionalization and transition metal catalysis, and allows the convenient and direct access to a variety of medicinally important 3-trifluoromethylpiperidine derivatives. This chemistry also represents a rare example of a direct trifluoromethylation of an internal olefinic C-H bond. A radical mechanism is proposed for this reaction.
