Two types of substrates are investigated which bear two acyl groups ortho to each other on a benzene ring. [ABSTRACT FROM AUTHOR]

This first formal [3+2] cycloaddition of α-trifluoromethyl-3-indolylmethanol silyl ethers and acyclic ketene dithioacetals furnishes trifluoromethylated cyclopenta[b]indoles. [ABSTRACT FROM AUTHOR]

The unique reactivity of α-(alkylideneamino)nitriles toward molecular oxygen is firstly revealed. [ABSTRACT FROM AUTHOR]

The polarity reversible nature of azomethine imines as the crucial transformation enables the title reaction sequence to proceed under mild, transition-metal-free conditions. [ABSTRACT FROM AUTHOR]

Treatment of the title substrate (I) with various ketene dithioacetals results in the formation of α-arylated β-ketothiolesters, nitriles, and carbonyl compounds via a tandem 1,3-carbothiolation/aromatization sequence. [ABSTRACT FROM AUTHOR]

The reaction of dithioacetals (I) with nitriles (II) followed by a zinc-mediated one-pot reaction of the isolable intermediate (V) leads to 5-ethylthiopyrroles (III), whilst the copper-mediated reaction of the intermediate (V) affords 4-ethylthiocarbonylpyrroles (IV) via a second isolable intermediate (VI).

Michael addition of N-(p-chlorobenzylidene)glycine methyl ester (II) with various enones is combined with cyclization during the workup on silica gel column chromatography to give polysubstituted pyrrolines (III)/(IV), (VI)/(VII) and (IX)/(X) as diastereomeric mixtures. [ABSTRACT FROM AUTHOR]
