Using gem-difluoromethylene alkynes as effectors, unprecedented diverse C-H activation/[4+2] annulations of simple benzoic acids are reported. The chemodivergent reaction outcomes are well-tuned by Rh/Ir-catalyzed system; in the Rh-III catalysis, 3-alkenyl-1H-isochromen-1-one and 3,4-dialkylideneisochroman-1-one skeletons are afforded in a solvent-dependent manner whereas difluoromethylene-substituted 1H-isochromen-1-ones are generated under the Ir-III-catalyzed system. Mechanistic studies revealed that unusually double beta-F eliminations and fluorine effect-induced regioselective reductive elimination are independently involved to enable distinct reaction modes for divergent product formations. Besides, synthetic application in both the derivatization of obtained diene products and the on-DNA synthesis of DNA-tagged difluorinated isocoumarin have been demonstrated, which manifested great potential for synthetic utility of the developed protocols.

Prized for their ability to reliably forge stereocenters with precise regiocontrol from simple and abundant starting materials, substrate-directable enantioselective reactions are widely used in modern organic synthesis. As such, enantioselective C(sp(3))-H functionalization reactions directed by innate functional groups could provide new routes to introduce molecular complexity within the inert hydrocarbon moiety, but to date this approach has been met with little success. While free primary aliphatic amines are common, versatile intermediates in synthesis, they are traditionally unreactive in C(sp(3))-H activation reactions. Herein we report the Pd-catalyzed enantioselective C(sp(3))-H functionalization of free aliphatic amines (cyclopropylmethylamines) enabled by a chiral bidentate thioether ligand. This ligand’s privileged bidentate coordination mode and thioether motif favor the generation of the requisite mono(amine)-Pd(II) intermediate, thus enabling the enantioselective C-H activation of free amines. The resulting C-Pd(II) species could engage in either Pd(II)/Pd(IV) or Pd(II)/Pd(0) catalytic cycles, enabling access to a diverse range of products through (hetero)arylation, carbonylation, and olefination reactions. Consequently, this versatile reactivity offers medicinal chemists a general strategy to rapidly prepare and functionalize biologically relevant amines.

Diene-transmissive Diels-Alder (DTDA) sequences are extraordinarily powerful processes for the generation of fused bicyclic systems. Nonetheless, only stable dienophiles have previously been deployed. Herein we report DTDA sequences with a variety of substituted [3]dendralenes in the first study to deploy arynes as dienophiles. We demonstrate the one-flask generation of complex, aromatic-ring-containing, multicyclic systems of relevance to medicinal chemistry. These synthetic operations provide numerous successful examples of the otherwise challenging and rarely reported intermolecular Diels-Alder reaction of acyclic 1,3-butadienes with arynes, which is made possible due to the exalted reactivity of dendralenic dienes.

Enantioselective electrophilic three-component thioarylation of alkenes by chiral selenide catalysis with free phenols as arylating sources is disclosed. A variety of chiral phenols were achieved in high regio-, enantio-, and diastereoselectivities. Mechanistic studies revealed that this transformation went through carbon nucleophilic attack to give the products rather than the process of intramolecular rearrangement of phenolic ether intermediates. The application of this organocatalytic method in the alkylation of methoxy-substituted benzenes elucidated its generality.

An easily handled one-pot synthetic procedure was previously developed for the synthesis of bisphosphinates starting from acyl chlorides. Herein, other trivalent derivatives as acid anhydrides and activated esters were tested to form various bisphosphinates. This modulation of the reactivity can be controlled according to the nature of the acid derivative for the use of sensitive and functionalized substrates.

In order to explore and develop new anticancer agents, three series of 2-phenylbenzimidazoles, 15-46, were condensed under simple and mild conditions using sodium metabisulfite as an oxidation agent and another series, 47-55, were obtained via a reduction reaction using sodium borohydride. All the compounds synthesized were evaluated for their in vitro anticancer activities against three human cancer cell lines. The novel compound 38 was found to be the most potent multi cancer inhibitor against A549, MDA-MB-231, and PC3 cell lines (IC50 values 4.47, 4.68 and 5.50 mu g mL(-1), respectively). In addition, compound 40 exhibited the best IC50 value of 3.55 mu g mL(-1) against the MDA-MB-231 cell line. The results demonstrated that introducing a new substituent to compounds 37-55 could improve their antiproliferative activities.
