Intrinsic chiral porphyrins

Ogoshi and coworkers have developed a new strategy for synthesis of a chiral porphyrin, in which an achiral porphyrin is modified to have C2 symmetry (an intrinsic chiral porphyrin) by introducing achiral substituents. In Figure 8 the Ct symmetric intrinsic chiral porphyrins are shown. A series of chiral porphyrins were prepared in...
