we developed a versatile method for [3+2] cycloaddition with diverse nitriles to yield substituted oxazoles. Our approach can be extended to bis-oxazoles, isotope-labeled oxazoles, drug diversification, as well as natural product and drug synthesis. Integration of photolysis with continuous-flow chemistry demonstrated applicability, scalability, and robustness for oxazole synthesis.
利用单线态卡宾,我们开发了一种与多种腈进行[3+2]环加成反应以产生取代恶唑的通用方法。我们的方法可以扩展到双恶唑、同位素标记恶唑、药物多样化以及天然产物和药物合成。光解与连续流化学的集成证明了恶唑合成的适用性、可扩展性和稳健性。
