Abstract

Reaction of 2-substituted 5- and 6-aminobenzoxazoles <strong>1</strong> and <strong>2</strong> with diethyl ethoxymethylenemalonate afforded the corresponding diethyl 3-<i>N</i>-(5- and 6-benzoxazolyl)aminomethylenemalonates <strong>3 </strong>and <strong>4</strong>. Under conditions of the Gould-Jacobs reaction, the compounds <strong>3 </strong>gave a mixture of angularly and linearly annelated oxazolo[4,5-<i>f</i>]quinolones <strong>5 </strong>and oxazolo[5,4-<i>g</i>]quinolones <strong>6</strong>, and compounds <strong>4 </strong>afforded a mixture of oxazolo[5,4-<i>f</i>]quinolones <strong>7 </strong>and oxazolo[4,5-<i>g</i>]quinolones <strong>8</strong>.
