Direct Access to Primary Amines from Alkenes by Selective Metal-Free Hydroamination

Direct and selective synthesis of primary amines from easily available precursors is attractive yet challenging. Herein, we report the rapid synthesis of primary amines from alkenes via metal-free regioselective hydroamination at room temperature. Ammonium carbonate was used as ammonia surrogate for the first time, allowing for efficient conversion of terminal and internal alkenes into linear, α-branched, and α-tertiary primary amines under mild conditions. This method provides a straightforward and powerful approach to a wide spectrum of advanced, highly functionalized primary amines which are of particular interest in pharmaceutical chemistry and other areas.

Nucleophilic RhI Catalyzed Selective Isomerization of Terminal Aziridines to Enamides

The selective isomerization of various terminal N-Boc protected aziridines to enamides was realized using the highly reactive nucleophilic rhodium catalyst C with the Lewis acid LiNTf2 as co-catalyst under moderate conditions. The reaction proceeds smoothly with only 1 molpercent catalyst loading and excellent yields were achieved. An intermediate containing an enamide with a non-conjugated terminal C=C double bond was detected during the course of the reaction, which isomerizes to form the thermodynamically favored 2-amido styrene. Mechanistic insight is gained based on these observations.

Regioselective Fluorination of α-Hydroxy-β-aminophosphonates by Using PyFluor

We report a simple protocol for the synthesis of α-fluoro-β-aminophosphonates by the regioselective fluorination of α-hydroxy-β-aminophosphonates under mild conditions. The fluorination reactions were mediated by the PyFluor reagent and occurred with the retention of configuration. The main products of this reaction were a series of α-fluoro-β-aminophosphonates, which can be used as precursors in the preparation of medicinally important compounds (e.g., dipeptide analogues).

Ligand, metal complex containing ligand, and reaction using metal complex containing ligand

A hydrogen transfer reaction may be more efficiently promoted by using a metal complex represented by Formula (2): (wherein, R1 to R8 are the same or different, and each represents a hydrogen atom, a substituted or unsubstituted alkyl group or the like; or wherein; R1 and R2, R2 and R3, R3 and R4, R4 and R5, and R5 and R6 are respectively bonded to each other to form a bivalent hydrocarbon group; R9 are the same or different, and each represents an alkyl group or cycloalkyl group; M is ruthenium (Ru) or the like; X is a ligand; and n is 0, 1 or 2). More specifically, the metal complex enables a hydrogenation reaction of various substrates having a stable carbonyl group or the like to be advanced with a high yield under mild conditions.

The compounds of the invention are also effective for reducing inflammation and may be used alone or in combination with other analgesics.

Probing o-diphenylphosphanyl benzoate (o-DPPB)-directed C - C bond formation: Total synthesis of dictyostatin

Herein, we report a robust total synthesis of dictyostatin. This polyketide natural product has attracted much attention because of its impressive antiproliferative activity against several human cancer-cell lines. We accomplished its synthesis in a highly convergent manner from three fragments of equal complexity, which were prepared on multigram scale. The southern and northwestern subunits were constructed through application of our o-DPPB-directed hydroformylation and allylic substitution methodology, respectively. These methods generated the C6 and C14 stereocenters of dictyostatin with good diastereoselectivities and simultaneously allowed further elaboration of the fragments by Wittig olefination and Sharpless asymmetric epoxidation, respectively. The compelling performance of the hydroformylation and allylic substitution with regard to practicability, selectivity, and scale underline their value for the construction of propionate motifs.

Bis(amidate)bis(amido) titanium complex: A regioselective intermolecular alkyne hydroamination catalyst

An efficient and selective bis(amidate)bis(amido) titanium precatalyst for the anti-Markovnikov hydroamination of alkynes is reported. Hydroamination of terminal and internal alkynes with primary alkylamines, arylamines, and hydrazines is promoted by 5-10 mol % of Ti catalyst. Various functional groups are tolerated including esters, protected alcohols, and imines. The in situ generated complex shows comparable catalytic activity, demonstrating its synthetic versatility for benchtop application. Applications of this catalyst for the synthesis of amino alcohols and a one-pot procedure for indole synthesis are described. A mechanistic proposal that invokes turnover-limiting protonolysis is presented to rationalize the observed regioselectivities.
