The title compound, hydantoin-l-proline, C6H8N 2O2, crystallize in the orthorhombic system with space group P212121 (N°19), Z = 4, and unit cell parameters a = 7.136(1) A, b = 8.009(2) A, c = 11.378(2) A. The molecular structure shows a hydantoin and pyrrolidine ring coupling forming a bicyclohydantoin. The crystal packing is governed by N-H???O hydrogen bond-type intermolecular interactions, forming infinite one-dimensional chains.

A general Cu-catalyzed, regioselective method for the N-3-arylation of hydantoins is described. The protocol utilizes aryl(trimethoxyphenyl)iodonium tosylate as the arylating agent in the presence of triethylamine and a catalytic amount of a simple Cu-salt. The method is compatible with structurally diverse hydantoins and operates well with neutral aryl groups or aryl groups bearing weakly donating/withdrawing elements. It is also applicable for the rapid diversification of pharmaceutically relevant hydantoins.

A versatile synthesis of 1,4-benzodiazepine derivatives through the reaction of various 3-(trifluoromethanesulfonyloxy)benzynes with N -(p -toluenesulfonyl)imidazolidin-2-ones is reported. This reaction system provides a 1,4-benzodiazepine bearing a trifluoromethanesulfonyloxy group as a single regioisomer among the four possible regioisomers.
