A range of 3H-indoles and 2H-benzo[b][1,4]thiazines smoothly undergo asymmetric Strecker reaction with ethyl cyanoformate in the presence of a Cinchona alkaloid-based thiourea catalyst at 10 °C to give structurally diverse nitrogen-containing heterocycles in good to excellent yields and with excellent ee.
A Brønsted acid catalyzed highly diastereoselective three‐component cascade reaction of 3H‐indoles, oxazol‐5‐(4H)ones and water is reported. The reaction proceeds under mild conditions with broad substrate scope to give the desired products in high yields.
