The intermolecular deacylative coupling of unstrained ynones via C-C bond activation was accomplished by a CuCl-bpy system undermild reaction conditions. This protocol features facile cleavage of the C-C bond at room temperature, broad substrate scope, and efficient construction of important symmetric and unsymmetrical 1,3-diyne adducts through homo or cross coupling of ynones, respectively. The preliminary

The present invention relates to compounds of formula (I): and to salts thereof, wherein R1-R6 have any of the values defined in the specification, and compositions and uses thereof. The compounds are useful as inhibitors of TAF1. Also included are pharmaceutical compositions comprising a compound of formula (I) or a pharmaceutically acceptable salt thereof, and methods of using such compounds and salts in the treatment of various TAF1-mediated disorders.
Construction of Chiral Tri‐ and Tetra‐Arylmethanes Bearing Quaternary Carbon Centers: Copper‐Catalyzed Enantioselective Propargylation of Indoles with Propargylic Esters
Copper‐catalyzed enantioselective propargylation of indoles with propargylic esters and sequential Huisgen cycloaddition with azides lead to the construction of chiral triarylmethanes, bearing a quaternary carboncenter, with high to excellent enantioselectivities. The result described herein can be used in the enantioselective preparation of a tetraarylmethane.
The instant invention provides compounds of Formula I which are leukotriene biosynthesis inhibitors.
Compounds of Formula I are useful as anti-atherosclerotic, anti-asthmatic, anti-allergic, anti-inflammatory and cytoprotective agents.

We report a Zn‐ProPhenol catalyzed asymmetric Mannich reaction between butenolides and polyfluorinated alkynyl ketimines to obtain vinylogous products featuring two contiguous tetrasubstituted stereogenic centers. Notably, this is the first successful use of ketimines in the ProPhenol Mannich process, and the reaction offers a new approach for the preparation of pharmaceutically relevant products possessing
