β¦ Synopsis
The photodimeri2ation of anthracene derivatives such as 2anthracenesulfonate or 2-anthracenecarboxylate in aqueous solution was found to proceed regio-and stereoselectively in the presence of E-CyD and y-f&D, respectively.
These reaction selectivities were explained in terms of specific inclusion of these compaunds into CyDs.

## Abstract magnified image Asymmetric 1,3βdipolar cycloadditions of chiral nitrones to 1βpropeneβ1,3βsultone (**1**) were investigated. Chiral nitrones **6aβe** reacted with sultone **1** in toluene at 90 Β°C for 24β36 h to give the corresponding isoxazolidines in moderate yields with high regiose
