Alkynylation of aldehydes with alkynyl(aryl)iodonium salts catalyzed by an N-heterocyclic carbene (NHC) has been developed. The application of the organocatalyst and the hypervalent iodine group transfer reagent allowed for metal-free C-H functionalization and C-C bond formation. The reaction proceeds under mild conditions, at -40 C and in the presence of an amine base, providing access to an array of heteroaryl-propargyl ketones containing various substituents in good to excellent yields. The mechanism of the reaction was investigated by means of both experiments and density functional theory calculations. 13C-labeling and computations determined that the key alkynyl transfer step occurs via an unusual direct substitution at an acetylenic carbon, wherein an iodine-based leaving group is exchanged by a Breslow intermediate nucleophile. Moreover, kinetic studies revealed that the turnover-limiting step of the catalytic cycle is the generation of the Breslow intermediate, whereas the subsequent C-C bond formation is a fast process. These results are fully reproduced and rationalized by the calculated full free energy profile of the reaction, showing that the largest energy span is located between the protonated form of NHC catalyst and the transition state for the carbene attack on the aldehyde substrate.

The palladium-catalyzed, copper-promoted cross-dehydrogenative-coupling (CDC) of electron-deficient thiazoles with azine N-oxides through dual C-H activations was developed. It was found that copper(II) pivalate was an efficient dual-function reagent for the oxidative cross-coupling reactions, playing the roles of both an oxidant and a C-H bond activation promoter. This methodology provides a simple way to construct 2-thiazolyl pyridine moiety.

A variety of analogues of 1-[4-methoxy-3,5-dimethylbenzyl]-4-[3- (ethylamino)-2-pyridyl]piperazine hydrochloride (U-80493E) were synthesized and evaluated for their inhibition of human immunodeficiency virus type 1 (HIV-1) reverse transcriptase (RT). Replacement of the substituted aryl moiety with various substituted indoles provided bis(heteroaryl)piperazines (BHAPs) that were 10-100-fold more potent than U-80493E. The pyridyl portion of the lead molecule was found to be very sensitive to modifications. Extensive preclinical evaluations of several of these compounds led to the selection of 1-[(5-methoxyindol-2-yl)carbonyl]-4-[3-(ethylamino)-2- pyridyl]piperazine methanesulfonate (U-87201E, atevirdine mesylate) for clinical evaluation.
