Rhodium-catalyzed [2+2+2] cycloaddition of carbon disulfide to o,N-dialkynyltosylanilines gives two isomeric indolothiopyranthiones, a violet and a red isomer. This is the first crystal structure of a red isomer, which crystallizes with one solvent m

The title compound, C19H15NO2S3, is the first example of a dithia analogue of pyrano[3,4-b]indolone. The almost planar thiopyranoindolethione ring system (r.m.s. deviation for all non-H atoms = 0.030 Å) makes a dihedral angle of 80.70 (8)° with the

Enyne-substituted benzoisothiazole derivatives have been synthesised under one-pot, operationally simple conditions using 2-iodo-N-(trimethylsilylethynyl)benzenesulfonamides and terminal alkynes as starting materials and a palladium–copper-based ca

A series of 2-pyrazolines (3a-d) were obtained by reaction 1,3-dipolar cycloadditions of α,β-unsaturated cyclohexanone derivatives (2a-c) with hydrazine hydrate and 4-nitrophenylhydrazine in the presence of acetic acid and ethanol as solvents. The

The total syntheses of the carboline alkaloids perlolyrine and "isoperlolyrine" are reported. Key-steps of the syntheses are Negishi coupling reactions on alkynylynamides and their metal-catalyzed [2+2+2] cycloadditions with nitriles to form the β-

In non-racemic (1R,2R)-(1,2-dialkyl)-1,2-diaminocyclohexane palladium dichloride complexes the C2 symmetry of the diamine ligand is broken, resulting in selective R,S-coordination.
