Malaria parasites have three genomes: a nuclear genome, a mitochondrial genome, and an apicoplast genome. Since the apicoplast is a plastid organelle of prokaryotic origin and has no counterpart in the human host, it can be a source of novel targets for a
Palladium-Catalyzed Carbamoyl-Carbamoylation/ Carboxylation/Thioesterification of Alkene-Tethered Carbamoyl Chlorides Using Mo(CO)6 as the Carbonyl Source

We reported a palladium-catalyzed carbamoyl-carbamoylation/carboxylation/thioesterification of alkene-tethered carbamoyl chlorides using Mo(CO)6 as the carbonyl source. The reactions were typically performed with good functional group compatibility and tolerated different nucleophiles (amines, alcohols, phenols, thiols and water), which provided a new access to amidated/esterificated/thioesterificated/carboxylated oxindoles or lactams bearing an all-carbon quaternary stereocenter under CO gas-free conditions. Furthermore, natural product mutation and divergent late-stage derivatization are the important practical features.
Ruthenium Metathesis: A Key Step to Access a New Cyclic Tetrasubstituted Olefin Platform

An rapid and mild synthetic route for the preparation of cyclic tetrasubstituted platforms via ruthenium-catalyzed ring-closing metathesis (RCM) has been developed. This process tolerates a wide range of functionalities such as nitrogen, oxygen, sulfur, silicon, and carbon tethered groups, as well as very challenging fluorine and boron atoms (36 derivatives, up to 96%). This diversity-oriented method was further demonstrated by the postfunctionalization reactions, such as Pd-couplings, N-substitution, and reductive amination introducing a morpholine moiety.
Pd-catalyzed regiodivergent synthesis of diverse oxindoles enabled by the versatile heck reaction of carbamoyl chlorides

We report herein a miscellaneous oxindole synthesis bearing an all-carbon quaternary center, enabled by Pd-catalyzed intramolecular cyclization followed by multiple intermolecular Heck reactions of both easily accessible alkene-tethered carbamoyl chlorides and olefins. This protocol obviates the use of prefunctionalized olefinic reagents, exhibits excellent functional group tolerance, and features fascinating reactive versatility.
Enantioselective Construction of Tertiary Fluoride Stereocenters by Organocatalytic Fluorocyclization

1,1-Disubstituted styrenes with internal oxygen and nitrogen nucleophiles undergo oxidative fluorocyclization reactions with in situ generated chiral iodine(III)-catalysts. The resulting fluorinated tetrahydrofurans and pyrrolidines contain a tertiary carbon-fluorine stereocenter. Application of a new 1-naphthyllactic acid-based iodine(III)-catalyst allows the control of tertiary carbon-fluorine stereocenters with up to 96% ee. Density functional theory calculations are performed to investigate the details of the mechanism and the factors governing the stereoselectivity of the reaction.
Aminoxyl-Catalyzed Electrochemical Diazidation of Alkenes Mediated by a Metastable Charge-Transfer Complex
Siu, Juno C.,Parry, Joseph B.,Lin, Song
supporting information, p. 2825 - 2831 (2019/02/14)
We report the development of a new aminoxyl radical catalyst, CHAMPO, for the electrochemical diazidation of alkenes. Mediated by an anodically generated charge-transfer complex in the form of CHAMPO-N3, radical diazidation was achieved across a broad scope of alkenes without the need for a transition metal catalyst or a chemical oxidant. Mechanistic data support a dual catalytic role for the aminoxyl serving as both a single-electron oxidant and a radical group transfer agent.
Ligand-Promoted Iron(III)-Catalyzed Hydrofluorination of Alkenes
Xie, Yongtao,Sun, Peng-Wei,Li, Yuxin,Wang, Siwei,Ye, Mengchun,Li, Zhengming
, p. 7097 - 7101 (2019/04/17)
An iron-catalyzed hydrofluorination of unactivated alkenes has been developed. The use of a multidentate ligand and the fluorination reagent N-fluorobenzenesulfonimide (NFSI) proved to be critical for this reaction, which afforded various fluorinated comp
Direct Hydrofluorination of Methallyl Alkenes Using a Methanesulfonic Acid/Triethylamine Trihydrofluoride Combination
