Photoassisted Synthesis of Complex Polyheterocycles via Rational Design of Tailored Photoprecursors
… is the [4+2] intramolecular cycloadditions of azaxylylenes, which are developed through standard amide bond-forming reactions. The intermediates are produced by the excited state intramolecular proton transfer (ESIPT) from photoprecursors that could be trapped intramolecularly by tethered …

Photoassisted Generation of Complex N, O, S Polyheterocycles
<p>This research set out to continue the exploration and diversification of excited state <em>o</em>-azaxylylene cycloadditions, utilizing both pre-photochemical and post-photochemical modifications.</p> <p>Pre-photochemical modifications came through the addition of heteroatoms, namely nitrogen …
