Tuneable access to indole, indolone, and cinnoline derivatives from a common 1,4-diketone Michael acceptor

A convergent strategy is reported for the construction of nitrogen-containing heterocycles from common substrates: 1,4-diketones and primary amines. Indeed, by just varying the substrates, the substituents, or the heating mode, it is possible to selectively synthesize indole, indolone (1,5,6,7-tetrahydroindol-4-one), or cinnoline (5,6,7,8-tetrahydrocinnoline) derivatives in moderate to excellent yields.

Fe-Catalyzed Cycloisomerization of Aryl Allenyl Ketones: Access to 3-Arylidene-indan-1-ones

A cycloisomerization of aryl allenyl ketones to 3-arylidene-indan-1-ones using a cationic Fe-complex as a catalyst is reported. The catalyst opens a synthetically interesting reaction pathway to this surprisingly underrepresented class of indanones that are not accessible using alternative catalytic systems.

Elongated phosphoranes by C-C coupling of haloaroylmethylidene-triphenylphosphoranes: Synthesis and applications

Haloaroylmethylidenephosphoranes 3 can be subjected to Pd(o) mediated C-C coupling reactions to yield diaryl-, arylhetaryl-, dihetaryl, arylethenylaryl/hetaryl- and arylethynylaryl/hetaryl-carbonylmethylidenephosphoranes 4-9. Suzuki-Kumada reactions can a
