Witt, A. published the artcileSynthesis and Reactions of some 2-Vinyl-3H-quinazolin-4-ones, HPLC of Formula: 18791-02-1, the publication is Tetrahedron (2000), 56(37), 7245-7253, database is CAplus.
A simple, high-yielding synthesis of 2-vinyl-3H-quinazolin-4-one, 2-(1-chlorovinyl)-3H-quinazolin-4-one, and 2-(1-bromovinyl)-3H-quinazolin-4-one is reported. The 2-vinylquinazolinones participate readily in nucleophilic addition reactions. Treatment with both carbon and nitrogen nucleophiles results in a clean conversion into a variety of 2-substituted 3H-quinazolin-4-one derivatives 2-(1-Halovinyl)-3H-quinazolin-4-ones reacted with carbon nucleophiles to give several derivatives of 2-substituted 3H-quinazolin-4-one.
