要旨

The first example of N-aryl-δ-valerolactam synthesis via an intramolecular ring rearrangement reaction of 1-arylamino-2-oxocyclopentane-1-carbonitrile promoted by phenyliodine bis(trifluoroacetate) (PIFA) was reported. We show that this unprecedented regio-selective ring-rearrangement reaction driven by hypervalent iodine (PIFA) involves C5–H elimination, C1–C2 bond opening, and C1–N bond rearrangement steps and restraining the leaving tendency of the CN group. The structure of the lactam was further confirmed by single crystal X-ray diffraction (XRD) analysis. The present protocol showed a diverse array of functional group tolerance under the reaction conditions and offered good to excellent yields of lactams.

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.
