Turriane family

Fig. 1 Naturally occurring cyclophane derivatives belonging to the Turriane family...

The first total synthesis of three naturally occurring cyclophane derivatives belonging to the turriane family of natural products was also described by A. Furstner et al These natural products have a sterically hindered biaryl moiety and saturated as well as unsaturated macrocyclic tethers. Stereoselective entry to this class of compounds is possible using RCAM followed by Lindlar reduction of the resulting cycloalkynes.
