要旨

A base controlled regioselective 1,6-cyanoallylation of suitably functionalized 2H-pyran-2-ones has been demonstrated for the synthesis of various multi-substituted benzenes through a tandem process. We observed that lithium hydroxide provides a major product from α-attack and a minor product from γ-attack of allyl cyanide, while the use of sodium hydride as a base exclusively provides the product by γ-attack of allyl cyanide. We have also performed NMR experiments to understand the mechanistic pathway. The structure of the compound was confirmed by single crystal X-ray analysis.

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.
