✦ Synopsis

The absolute configuration of the title tetracyclic bis-oxazine, C 14 H 17 N 3 O 5 S, has been determined. It is an unexpected product from the attempt to synthesize a new class of bisoxazolines. The seven-membered lactam ring exhibits four axial (O and N) and one equatorial (S) substituents. The ortho-condensed and cis-configurated oxazine rings are positioned on opposite sides of the lactam ring.

The title compound, C 27 H 34 ClNO, was synthesized by a direct condensation reaction. The molecule has three chiral centres, which exhibit R, S and R absolute configurations, respectively. Two six-membered rings with different conformations coexist in the structure and they form a trans ring juncti

In the title compound, C 22 H 21 NO 5 , the pyrrolidine ring and the five-membered ring in the indene group have envelope conformations, while the furan ring adopts a twist conformation. Weak intermolecular C-HÁ Á ÁO interactions link the molecules into centrosymmetric dimers. The crystal packing is
