Cleavage of the C–C triple bond of ketoalkynes: synthesis of 4(3H)-quinazolinones†
Abstract
A novel protocol for the synthesis of 4(3H)-quinazolinones via selective cleavage of the triple bond of ketoalkynes under oxidant-, metal-, and ligand-free conditions has been developed. Various 4(3H)-quinazolinones were obtained through fragmentation of the C–C triple bond and formation of two C–N bonds.
