摘要：

A fast and facile procedure for one flask synthesis of (Z)-2-substituted-4-arylmethylene-2-oxazolin-5-ones (3) which are popularly known as Erlenmeyer azlactones, is being reported starting from N-acylglycines (1) and different aromatic aldehydes using arylsulphonyl chloride as cyclocondensing agent in the presence of triethyl amine base and dry benzene. The reaction time is reduced to minute under milder conditions alongwith higher yields of the products.
