要旨

A silver catalyzed domino reaction of N-cyanamide alkenes and 1,3-dicarbonyls including 1,3-diketones and ethyl acetoacetate has been developed for the facile synthesis of quinazolinones. In the presence of AgNO3/K2S2O8, the diketones could be converted to radicals and coupled with N-cyanamide alkenes to undergo a cyclization cascade for accessing quinazolinones. This method features mild reaction conditions, readily available starting materials, and valuable synthetic utility. Moreover, the products could be further transformed into various heterocycles.

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.
