Alkyl benzyl ketoximes react with acetylene at 60-150 deg C in MOH-dimethyl sulfoxide (M = Li, K) primarily by means of the methylene group of the benzyl grouping, which is primarily anti-oriented with respect to the hydroxy group, to give 2-alkyl-3-pheny

A highly efficient synthesis of chiral polysubstituted 2H-pyrrole derivatives via a Pd-catalyzed intermolecular asymmetric allylic dearomatization reaction of pyrroles is presented. With the commercially available palladium precursor and chiral ligand, the polysubstituted 2H-pyrrole products containing a chiral quaternary carbon center were obtained with up to 97% ee and >95/5 regioselectivity.

3-Arylpyrroles were synthesized by reduction of 3- and 4-pyrrolin-2-ones with 9-borabicyclo[3.3.1]nonane (9-BBN).

The cephalic extracts of the ant Anochetus kempfi were found to contain 2,5-dimethyl-3-isoamylpyrazine (1) and 3-methyl-4-phenylpyrrole (2). The structures of these compounds were established from their spectral data and by comparison with synthetic samples. This is the first report of a phenylpyrrole found in an insect and only the third report of a pyrrole from ants.

1-Aza-1,3-bis(triphenylphosphoranylidene)propane (3), prepared in situ by the reaction of 1-methyl>benzotriazole (betmip, 4) with methylidenetriphenylphosphorane followed by treatment with butyllithium, enables convenient preparations of 3H-2-benzazepine (7), 2,3-diarylpyrroles 8, and primary allylamines 12 and 13.
