要旨

The polyphosphoric acid-mediated reaction of 2-(2-aminophenyl)indenes with nitroalkenes was tested in the frame of synthetic studies towards CDK inhibitors with the paullone core. Unexpectedly, this reaction proceeded via a different mechanistic pathway affording derivatives of the natural alkaloid isocryptolepine. The scope of this unusual transformation was investigated and a mechanistic rationale explaining this outcome is offered.

Organic & Biomolecular Chemistry (OBC) publishes original and high impact research and reviews in organic chemistry. We welcome research that shows new or significantly improved protocols or methodologies in total synthesis, synthetic methodology or physical and theoretical organic chemistry as well as research that shows a significant advance in the organic chemistry or molecular design aspects of chemical biology, catalysis, supramolecular and macromolecular chemistry, theoretical chemistry, mechanism-oriented physical organic chemistry, medicinal chemistry or natural products. Articles published in the journal should report new work which makes a highly-significant impact in the field. Routine and incremental work is generally not suitable for publication in the journal. More details about key areas of our scope are below. In all cases authors should include in their article clear rationale for why their research has been carried out.
