(Chemical Equation Presented) Stereocontrol in the synthesis of dinuclear metal complexes of sulfinylcalixarenes 2 has been achieved by the arrangement of sulfinyl functionalities. Thus, the treatment of the rtct isomer of 2 (2rtct) with an excess of Et3B affords syn dinuclear boron complex 4, while a similar treatment of rctt and rcct isomers 2rctt and 2rcct yields anti dinuclear complexes 5 and 6, respectively.
