Xantphos is one of the two most common ligands used in palladium catalyzed Buchwald-Hartwig amination reactions, because of its broad scope and high probability of success. It does not, however, work well with unactivated aryl chlorides. Herein NIXANTPHOS is compared to Xantphos and an array of mono- and bidentate phosphines. NIXANTPHOS outperforms Xantphos and all other bidentate ligands examined. Under the optimal reaction conditions, unactivated aryl chlorides afford the expected products in good to excellent yield with as low as 0.05 mol% (500 ppm) palladium loading.

A green Barluenga-Valdes cross-coupling reaction for the synthesis of 1,1-diarylethylenes using palladium catalysis has been developed. The new catalytic system based on Pd/Xphos-SO3Na or Pd/MeDavephos-CF3SO3 in PEG/H2O under microwave irradiation was found to be the best conditions for this transformation. The recyclability of the palladium catalyst system was also studied, and it was found to be active over nine runs without significant loss in its activity.

Previously our group reported synthetic efforts used to synthesize kilogram quantities of the cholesteryl ester transfer protein (CETP) inhibitor torcetrapib, 1, via a mid-stage resolution. This account describes research conducted to develop an asymmetric route to this clinical candidate suitable for long-term manufacturing. The first asymmetric center is established via coupling of (R)-3-aminopentanenitrile to a trifluoromethylarene. After elaboration of the nitrile to a suitable precursor, a key step in the synthesis is diastereoselective cyclization of immonium ion 7 to provide the tetrahydroquinoline core. This approach also permitted a streamlined sequence to complete the synthesis of 1. Development of the process and synthetic rationale are described.

A new ferrocene-based ligand, 4,6-dimethyl-2-pyrimidinylferrocene (1), was conveniently prepared via the coupling reaction of chloromercuriferrocene and 4,6-dimethyl-2-iodopyrimidine, and its mono-phosphine-palladacycle complexes 3-6 were also readily obtained from the cyclopalladation reactions and bridge-splitting reactions. These compound have been fully characterized by 1H NMR, 13C{1H} NMR, IR, ESI-MS, and elemental analysis. Additionally, their detailed structures have been determined by X-ray single-crystal diffraction, and many types of intramolecular and intermolecular hydrogen bonds are found to exist in the crystals of these palladacycles. The catalytic activity of these air- and moisture- stable palladacycles was evaluated in the Buchwald-Hartwig amination involving a range of stoically hindered aryl chlorides. 5 and 6 were found to be very efficient for this reaction. Typically, using 1 mol % of catalyst in the presence of 2 equiv of KtOBu as base in PEG-400 [poly(ethylene glycol-400)] at 120 C provided coupling products in excellent yields. Moreover, the 6/PEG-400 system could be recycled and reused three times without any loss of catalytic activity.

The isoquinoline alkaloids isolated from the genus Corydalis possess potent and diverse biological activities. Herein, a concise, divergent, and enantioselective route to access these natural products is disclosed. Key transformations of our approach include a challenging Zn-ProPhenol-catalyzed asymmetric Mannich reaction to build a quaternary stereogenic center and a rapid cationic Au-catalyzed cycloisomerization to the common structural skeleton of these natural products. Subsequent late-stage oxidations and modifications allow efficient access to the targeted alkaloids. Overall, seven natural products have been successfully synthesized in 6 to 10 steps from readily available starting materials, including (+)-corynoline, (+)-anhydrocorynoline, (+)-12-hydroxycorynoline, (+)-12-hydroxycorynoloxine, (+)-corynoloxine, (+)-6-acetonylcorynoline, and (+)-bulleyanaline.
