摘要：

A one - pot condensation of perhydro-1,3 heterocycles - aldehyde equivalents with ethyl acetoacetate and ureas provides a convenient synthesis of the title compounds with a variety of substituents at C-4. Yields are equivalent or significantly higher than the conventional methods. (C) 1999 Elsevier Science Ltd. All rights reserved.
