A main group-catalyzed method for the synthesis of aryl- and heteroarylamines by intermol. C-N coupling is reported. The method employs a small-ring organophosphorus-based catalyst (1,2,2,3,4,4-hexamethylphosphetane) and a terminal hydrosilane reductant (phenylsilane) to drive reductive intermol. coupling of nitro(hetero)arenes with boronic acids. Applications to the construction of both Csp2-N (from arylboronic acids) and Csp3-N bonds (from alkylboronic acids) are demonstrated; the reaction is stereospecific with respect to Csp3-N bond formation. The method constitutes a new route from readily available building blocks to valuable nitrogen-containing products with complementarity in both scope and chemoselectivity to existing catalytic C-N coupling methods.

The ring-opening polymerization (ROP) of lactones is an effective method for the preparation of biocompatible and biodegradable aliphatic polyesters, for which the development of efficient organocatalysts with high activity and good controllability is highly desirable. A series of novel pyridyl-urea catalysts was synthesized and applied in the solvent-free ROP of lactones and trimethylene carbonate. Combined with 7-methyl-1,5,7-triazabicyclo[4.4.0]dec-5-ene (MTBD), the pyridyl-urea/MTBD systems showed a fast and living/controlled behavior in the ROP, generating polymers with narrow mol. weight distributions. The influences of catalyst structure, type of base, pyridyl-urea/base ratio, feed ratio of monomer/initiator and reaction temperature on the catalytic properties were investigated. A possible mechanism was proposed on the basis of NMR titration and dilution experiments

Keywords: indole boronate ester allylic acetate palladium allylation boronate rearrangement; indoline stereoselective preparation. We’ll tell you more about this compound (cas:1265884-98-7).

A three-component coupling using lithiated indoles, boronate esters and allylic acetates generates chiral indolines with adjacent quaternary stereocenters. Successful stereocontrol required the use of phosphoramidite ligands not previously described for organopalladium chem. Mechanistic studies indicate a monodentate PdL intermediate, and a stepwise allylation-aryl/alkyl migration. A protodeborylation strategy was used to install a C-H bond in place of the C-B bond. A photoredox coupling was used to replace C-B bond with a C-C bond in a highly diastereoselective manner. In the specific case of methyl-vinyl ketone, a novel radical-mediated annulation provides polycyclic products with high enantio- and diastereoselectivity.

Electron impact ionization of 5-[(cyanomethyl)sulfanyl]-substituted pyrroles generates low-stability mol. ions {M+., Irel 4-22%; compared to Irel 16-69% for 5-[(1,3-dioxolan-2-ylmethyl)sulfanyl] analogs} whose primary fragmentation involves cleavage of the C-S bond with expulsion of NCCH2 radical. Other fragmentation pathways of the mol. ions include formation of [M – CHR4]+. ions (R4 = CN) and substituent decomposition products. The mass spectra of 5-[(1,3-dioxolan-2-ylmethyl)sulfanyl]pyrroles characteristically show [M – SCH2R4]+ ion peak. The most intense ion peaks in the chem. ionization mass spectra of 5-[(cyanomethyl)sulfanyl] derivatives are those of M+. (Irel 18-69%) and [M + H]+ (Irel 34-100%). Both 5-[(cyanomethyl)sulfanyl]- and 5-[(1,3-dioxolan-2-ylmethyl)sulfanyl]pyrroles decompose mainly through cleavage of the CH2-S and C5-S bonds with the formation of stable [M – CH2R4]+ (Irel 92-100%), [M + H – CH2R4]+.
