1. Acylaminoacetyl derivatives of active methylene compounds.1. The cyclization of the benzoylaminoacetyl derivatives to α-substituted tetramic acids

2. The long known trivial name of tetramic acid is used to denote the pyrrolidine-2,4-dione and its tautomeric 4-hydroxy-3-pyrrolin-2-one structures.

4. Chem. Ber., 102, 2153 (1969).

5. This compound has been formulated [4] as l-acetyl-3-acetamino-pyrrolidine-2,4-dione. However, its pmr spectrum (see Experimental) clearly indicates the pyrrolinone structure 5.
