Palladium-catalyzed cyclocondensation of an aryl iodide with N-tosyl-2-(prop-2′-ynyloxy)aniline at room temperature is shown to constitute a convenient general method for the synthesis of (E)-3-arylidene-3,4-dihydro-2H-1,4-benzoxazines in moderate to very good yields. The method could also be extended to the synthesis of (E)-3-arylidene-2H-naphth[1,2-b][1,4]oxazines. The regio- and stereo-selectivity of the process, short reaction time, operational simplicity, and use of inexpensive starting materials represent its attractive features.

A new, one-pot palladium catalyzed reaction has been developed for the general synthesis of (E)-3-arylidene-3,4-dihydro-2H-1,4-benzoxazines at room temperature. The reaction procedure tolerates various functional groups. The method is characterized by reg
