SELECTIVE ANDROGEN RECEPTOR COVALENT ANTAGONISTS (SARCAS) AND METHODS OF USE THEREOF

This invention relates to selective androgen receptor covalent antagonists, synthetic intermediates and by-products, and related compounds, and compositions comprising the same, and uses thereof in treating androgen receptor dependent diseases and conditions such as hyperproliferations of the prostate including pre-malignancies and benign prostatic hyperplasia, prostate cancer, advanced prostate cancer, castration resistant prostate cancer, triple negative breast cancer, other cancers expressing the androgen receptor, androgenic alopecia or other hyperandrogenic dermal diseases, Kennedy's disease, amyotrophic lateral sclerosis (ALS), abdominal aortic aneurysm (AAA), and uterine fibroids, and to methods for reducing the levels of androgen receptor-full length (AR-FL) including pathogenic or resistance mutations, AR-splice variants (AR-SV), and pathogenic polyglutamine (polyQ) polymorphisms of AR.

Metal-Free Hydropyridylation of Thioester-Activated Alkenes via Electroreductive Radical Coupling

An electrochemical hydropyridylation of thioester-activated alkenes with 4-cyanopyridines has been developed. The reactions experience a tandem electroreduction of both substrates on the cathode surface, protonation, and radical cross-coupling process, resulting in a variety of valuable pyridine variants, which contain a tertiary and even a quaternary carbon at the α-position of pyridines, in high yields. The employment of thioesters to the conjugated alkenes enables no requirement of catalyst and high temperature, representing a highly sustainable synthetic method.

Copper-Photocatalyzed Contra-Thermodynamic Isomerization of Polarized Alkenes

The contra-thermodynamic isomerization of α- and β-substituted cinnamate derivatives catalyzed by the Cu(OAc)2/rac-BINAP complex under blue light irradiation is reported. The use of an oxazolidinone template, which favored the complexation of the copper catalyst to the substrate, allowed the E → Z isomerization of the catalytically formed chromophore under simple and robust reaction conditions in good to excellent ratios. The mechanism of this process based on the transient formation of a chromophore was also studied.

Design, synthesis and SARs of novel telomerase inhibitors based on BIBR1532

Telomerase has become one of the new popular targets for the development of anti-tumor drugs. Based on the structural characteristics of the BIBR1532 which has entered the stage of clinical research, six series total of 64 new compounds with diverse struc

Synergistic N-Heterocyclic Carbene/Palladium-Catalyzed [3 + 2] Annulation of Vinyl Enolates with 1-Tosyl-2-vinylaziridine

The synergistic combination of N-heterocyclic carbene organocatalysis and transition-metal catalysis for a formal [3 + 2] annulation between 3-substituted but-2-enoates and 1-tosyl-2-vinylaziridine was developed. This cooperative strategy provides a facile and efficient access to various functionalized (E)-3-ethylidene-4-vinylpyrrolidin-2-ones in a regioselective and stereoselective manner. The preliminary asymmetric studies were also performed, which indicated a potential for enantioselective annulation of vinyl enolate intermediates with transition-metal-π-allyl species.

Construction of Multi-Substituted Benzenes via NHC-Catalyzed Reactions of Carboxylic Esters

A carbene-catalyzed ester activation reaction for the synthesis of multi-substituted benzenes is developed. Tetra-substituted benzene compounds are efficiently synthesized through this methodology. Compared with aldehyde substrates used in previous reports, the ester substrates used here are much more readily available and inexpensive. In addition, the TEMPO oxidant used here is more inexpensive than the quinones commonly used in related carbene-catalyzed reactions.

Pd(II)/Bipyridine-Catalyzed Conjugate Addition of Arylboronic Acids to α,β-Unsaturated Carboxylic Acids. Synthesis of β-Quaternary Carbons Substituted Carboxylic Acids

Pd(II)/bipyridine-catalyzed conjugate addition of arylboronic acids to α,β-unsaturated carboxylic acids (including β,β-disubstituted acrylic acids) was developed and optimized, which provided a mild and convenient method for the highly challenging synthesis of β-quaternary carbons substituted carboxylic acids.

The DMAP-catalyzed [4 + 2] cycloaddition of α,β-unsaturated carboxylic acids with ketones furnishing α,β-unsaturated δ-lactones in good yields (up to 80%) is described, which is the first example of remote γ-C(sp3)-H activation of α,β-unsaturated carboxylic acids facilitated by DMAP, a pyridine-based catalyst.

N-Heterocyclic Carbene-Catalyzed Activation of Esters of N-Hydroxyphthalimide: A Highly Enantioselective Route to Chiral Dihydropyridinones Bearing an All Carbon Quaternary Stereogenic Center

An N-heterocyclic carbene-catalyzed highly enantioselective [3 + 3] annulation reaction of N-hydroxyphthalimide (NHPI) 3,3-disubstituted acrylates and N-Ts ketimines was developed. In most cases, the desired chiral dihydropyridinone products bearing an all carbon quaternary stereogenic center could be obtained in good yields with excellent enantioselectivities (>99% ee's), which demonstrated the NHPI acrylates as a kind of excellent substrate in NHC-catalysis.
