Asymmetric Cycloisomerization of o-Alkenyl-N-Methylanilines to Indolines by Iridium-Catalyzed C(sp3)?H Addition to Carbon?Carbon Double Bonds

Highly enantioselective cycloisomerization of N-methylanilines, bearing o-alkenyl groups, into indolines is established. An iridium catalyst bearing a bidentate chiral diphosphine effectively promotes the intramolecular addition of the C(sp3)?H bond across a carbon?carbon double bond in a highly enantioselective fashion. The reaction gives indolines bearing a quaternary stereogenic carbon center at the 3-position. The reaction mechanism involves rate-determining oxidative addition of the N-methyl C?H bond, followed by intramolecular carboiridation and subsequent reductive elimination.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 891782-60-8 is helpful to your research. Synthetic Route of 891782-60-8

Axial chirality control during suzuki-miyaura cross-coupling reactions: The tert-Butylsulfinyl group as an efficient chiral auxiliary

An efficient route to a new family of axially chiral biaryl ligands by a Suzuki-Miyaura cross-coupling reaction between ortho,ortho’-disubstituted aryl iodides bearing in ortho position a tert-butyl or p-tolylsulfinyl group and ortho-substituted phenyl boronic acids or esters is described. The comparison between the t-BuSO and p-TolSO groups as chiral controllers is reported. The modularity of the approach is demonstrated by the preparation of a variety of enantiopure axially chiral mixed S/N and S/P ligands.

1,6-Interactions between dimethylamino and aldehyde groups in two biphenyl derivatives

The interactions between the dimethyl amino and aldehyde groups in two biphenyl derivatives were studied. The use of the N-C bond length as an indicator of electrophilic behaviour of the group was demonstrated. The geometry of three molecular conformations of the compound were observed for the displacement of phenyl groups. Two molecular configurations were found suited for modelling the inrteractions between dialkyamino groups and aldehyded than a related naphthalene derivative.

Discovery of LSZ102, a potent, orally bioavailable selective estrogen receptor degrader (SERD) for the treatment of estrogen receptor positive breast cancer

In breast cancer, estrogen receptor alpha (ERalpha) positive cancer accounts for approximately 74% of all diagnoses, and in these settings, it is a primary driver of cell proliferation. Treatment of ERalpha positive breast cancer has long relied on endocrine therapies such as selective estrogen receptor modulators, aromatase inhibitors, and selective estrogen receptor degraders (SERDs). The steroid-based anti-estrogen fulvestrant (5), the only approved SERD, is effective in patients who have not previously been treated with endocrine therapy as well as in patients who have progressed after receiving other endocrine therapies. Its efficacy, however, may be limited due to its poor physicochemical properties. We describe the design and synthesis of a series of potent benzothiophene-containing compounds that exhibit oral bioavailability and preclinical activity as SERDs. This article culminates in the identification of LSZ102 (10), a compound in clinical development for the treatment of ERalpha positive breast cancer.

17O NMR studies of boronic acids and their derivatives

The group of 155 substituted phenylboronic acids and their derivatives: esters, boroxines and benzoxaboroles, were investigated by 17O NMR spectroscopy. The influence of substituents of phenylboronic acids on the 17O chemical shift was evaluated. For the compounds with substituents at the para position, excellent correlation with the Hammett constant was obtained. For the ortho-substituted compounds use of the Charton equation gave a good correlation of results. Surprisingly, meta-substituted compounds show none of the above-mentioned correlations. A series of boronic esters of alcohols, diols and hydroxyacids were synthesized. The influence of the structure of parent hydroxy compounds on the 17O chemical shift was discussed. Selected benzoxaboroles and boroxines were also investigated, and their chemical shifts were compared with those of boronic acids. 17O NMR spectroscopy was also used to investigate the equilibria in solution. Equilibrium of the reaction of selected boronic acids with hydroxyl anions in acetonitrile was determined by 17O and 11B titration experiments. Monomer-dimer equilibria were also studied. The experimental chemical shifts were compared with the results of theoretical calculations. Very good correlations were obtained for the ortho- and para-substituents, but not for the meta ones.

Probing the importance of the hemilabile site of bis(phosphine) monoxide ligands in the copper-catalyzed addition of diethylzinc to N-phosphinoylimines: Discovery of new effective chiral ligands

(Chemical Equation Presented) The hemilabile ligand Me-DuPHOS(O) 2 has proven to be a successful ligand for the copper-catalyzed addition of diethylzinc to N-phosphinoylimines. The corresponding alpha-chiral amines were obtained in high yields (80-98%) and enantiomeric ratios (19.0:1 to 99.0:1 er). Furthermore, this Cu?2 catalytic system has been shown to be effective in the addition of diethylzinc to nitroalkenes and in the reduction of beta,beta-disubstituted vinyl phenyl sulfones. This paper describes a general structure/selectivity study in which the three ligand subunits (chiral phospholane-linker-labile coordinating group (Z)) are systematically modified and tested in the copper-catalyzed addition of diethylzinc to the N-phosphinoylimine 1 derived from benzaldehyde. This study led to the discovery of a new class of effective chiral ligands that combine a chiral phospholane unit and an achiral phosphine oxide.
