pyrrole semiconductors and has been largely unexplored for electronics applications. Discrete monomers or oxazine polymers could serve as an efficient hole carrier for novel devices. A series of 1,4‐disubstituted cyclopenta[d][1,2]oxazines (R = tolyl, p‐nitrophenyl, t‐buytl, furyl, and 5‐methylthienyl) were isolated via ring closure with hydroxylamine from a 1,2‐acylcyclopentadiene precursor.
