Abstract
[Au]-catalyzed and substrate-dependent intramolecular cyclization of sulfonyl ene-amides with a pendant propargyl group afford tetrasubstituted pyrroles, o-aminophenols, or 1,6-dihydropyridine carbaldehydes. While the pyrroles and aminophenols are formed when the propargylic alkyne is terminal, dihydropyridines are formed when internal alkyne is present. Internal alkyne substrates with 2-thienyl and 3-thienyl groups give different types of dihydropyridines. The dihydropyridines so obtained can be readily converted to nicotinaldehydes with concomitant sulfonyl migration upon heating in xylene.

Abstract
RNA cap methylations have been shown to be crucial for the life cycle, replication, and infection of ssRNA viruses, as well as for evading the host's innate immune system. Viral methyltransferases (MTases) therefore represent an attractive target for the development of compounds as tools and inhibitors. In coronaviruses, N7-methyltransferase function is localized in nsp14, which has become an increasingly important therapeutic target with the COVID-19 pandemic. In recent years, we have been developing SAH-derived bisubstrates with adenosine and an N-arylsulfonamide moiety targeting both SAM and RNA binding sites in nsp14. We report here the synthesis of 31 SAH analogues with the N-arylsulfonamide attached to the 5'-position of adenosine via different linkers such as N-ethylthioether, N-ethylsulfone, N-ethylamino or N-methyltriazole. The compounds were obtained efficiently by amine sulfonylation or click chemistry. Their ability to inhibit SARS-CoV-2 N7-MTase was evaluated and the best inhibitors showed a submicromolar inhibitory activity against N7-MTase nsp14.

Abstract
The mechanism of iron-catalyzed intramolecular [2 + 2] cycloaddition and cycloisomerization of enyne acetates has been investigated with DFT computations. Both mechanisms start the catalytic cycle from the stepwise 1,2-acyloxy migration to afford the iron carbene. The [2 + 2] cycloaddition mechanism involves subsequent key steps of [2 + 2] cycloaddition, 1,2-acyloxy migration, and reductive elimination to generate the azabicyclo [3.2.0] heptane product, with the reductive elimination being the rate-determining step. The cycloisomerization mechanism involves subsequent key steps of [2 + 2] cycloaddition, stepwise 1,4-acyloxy migration to produce the allenylpyrrolidine product, with the 1,4-acyloxy migration being the rate-determining step. Reaction potential energy surfaces for two model substrates that have or do not have alkene-terminal substituents have been investigated and the origins of the selectivities have been disclosed. Moreover, energy profiles with three possible spin states (SFe = 0, 1, 2) have been considered. The reaction is suggested to occur mainly on the singlet potential energy surface with a few spin crossovers between singlet and triplet states involved, which indicates that this reaction should have two-state reactivity (TSR).

Abstract
Cycloisomerizations are powerful skeletal rearrangements that allow the construction of complex molecular architectures in an atom-economic way. We present here an unusual type of cyclopropyl enyne cycloisomerization that couples the process of a cycloisomerization with the activation of a C-C bond in cyclopropanes. A set of substituted non-canonical tricyclic cyclobutanes were synthesized under mild conditions using [(Ph3 P)2 Fe(CO)(NO)]BF4 as catalyst in good to excellent yields with high levels of stereocontrol.

Abstract
A conceptually novel reaction cascade is presented, which allows readily available enynes to be converted into functionalized 1,3-dienes comprising a stereodefined tetrasubstituted alkene unit; such compounds are difficult to make by conventional means. The overall transformation is thought to commence with formation of a metallacyclic intermediate that evolves via cleavage of an unstrained C-X bond in its backbone. This non-canonical cycloisomerization process is followed by a cross-coupling step, such that reductive C-C bond formation regenerates the necessary low-valent metal fragment and hence closes an intricate catalytic cycle. The cascade entails the formation of two new C-C bonds at the expense of the constitutional C-X entity of the substrate: importantly, the extruded group X must not be a heteroelement (X=O, NR), since activated β-C-C bonds can also be broken. This concern was reduced to practice in two largely complementary formats: one procedure relies on the use of alkyl-Grignard reagents in combination with catalytic amounts of Fe(acac)3, whereas the second method amalgamates cycloisomerization with Suzuki coupling by recourse to arylboronic acids and phosphine-ligated palladium catalysts.

Abstract
We report first Fe-catalyzed hydroborylative cyclization reaction. The process provides one C-C and one C-B bond in a single operation and shows a wide scope, allowing the formation of carbo- and heterocycles containing a homoallylic boryl unit that can be further functionalized. The reaction takes place in smooth conditions, with inexpensive catalytic system and full atom economy since HBpin is the borylation agent, in contrast to our previously reported Pd-catalyzed reaction. Both aryl and alkyl substituted alkynes are reactive, revealing a wide reaction scope. Mechanistic studies suggest the intermediacy of FeII -hydride active catalyst capable to react with the alkyne group prior to alkene insertion, and computational studies suggest the occurrence of barrierless σ-bond metathesis involving HBpin and Fe-C bonds along the catalytic cycle.
