(1b) with aldehydes. The Michael adducts 5/6 are obtained from 3/4 by reaction with malononitrile/LDA in THF at −78°C, or in DMSO with NaH at room temp. Reaction of 3/4 with malononitrile and methylate in methanol yielded the substituted nicotinonitriles 7/8. From terephthalaldehyde, the diketones 9 are prepared, which yield with malononitrile the phenylene‐bis[(thienyl/furyl)nicotinonitrile] derivatives

coupling of electron-deficient (hetero)aryl halides 1 and (hetero)aryl or alkenyl 1-propargyl alcohols 2 does not terminate at the stage of the expected internal propargyl alcohols, but rather gives rise to the formation of alpha,beta-unsaturated ketones 3 with a variety of acceptor substituents. This new domino reaction, a coupling-isomerization reaction (CIR), can be rationalized as a sequence of

Heteroaryl substituted cyclopropyl ketones were prepared by reactions with Me 3SO+ I+, and by reaction with Lewis acids they were transformed into substituted dihydrobenzo[ b ]furanone or -thiophenone, or γ-hydroxy ketones. Cycloadditions with thiophene derivatives allowed the synthesis of substituted benzo[ b ]thiophene derivatives, but with poor yields. Structures and stereochemistry were established mainly
