SYNTHESIS OF AMIDES AND AMINES FROM ALDEHYDES OR KETONES BY HETEROGENEOUS METAL CATALYSIS

A mild and efficient synthesis of primary amines and amides from aldehydes or ketones using a heterogeneous metal catalyst and amine donor is disclosed. The initial heterogeneous metal-catalyzed reaction between the carbonyl and the amine donor components is followed by the addition of a suitable acylating agent component in one-pot, thus providing a catalytic one-pot three-component synthesis of amides. Integration of enzyme catalysis allows for eco-friendly one-pot co-catalytic synthesis of amides from aldehyde and ketone substrates, respectively. The process can be applied to asymmetric synthesis or to the co-catalytic one-pot three-component synthesis of capsaicin and its analogues from vanillin or vanillyl alcohol. A co-catalytic reductive amination/dynamic kinetic resolution (dkr) relay sequence for the asymmetric synthesis of optically active amides from ketones is disclosed. Implementation of a catalytic reductive amination/kinetic resolution (kr) relay sequence produces the corresponding optically active amide product and optical active primary amine product with the opposite stereochemistry from the starting ketones.

Antiestrogen compounds

A genus of proteolysis-targeting chimeras (PROTACs)-type compounds/antiestrogens has now been found that act as selective estrogen receptor degraders (SERDs) and estrogen receptor antagonists by degrading and antagonizing ERa in breast cancer cells. The compounds are of the following genus: The compounds described herein exhibit anti-proliferative effects, and are potentially useful, alone or in combination with other therapies, for the treatment of breast cancer. In general, these compounds combine a tight binding ERa targeting ligand tethered to a recognition motif or degron. Once bound, the degron recruits destructive cellular components and the targeted receptor (i.e., ERa) is degraded (i.e., destroyed) or antagonized. ##STR00001##
