A chiral porphyrin and its reference porphyrins with features for binding of alpha-amino acid esters to hosts are synthesized. Three recognition groups, Zn, OH, and CH2CO2Me, are introduced into the porphyrin framework for binding experiments. Zn ion and the OH group stabilize the host-guest complex through coordination and hydrogen bonding interactions.

Bifunctional macrocycles and diamide are designed and synthesized. The analysis has shown the importance of the relative orientation of the binaphthyl moiety and the orthogonal disposition of the binaphthyl moiety in bifunctional macrocycle has brought the differential ring-current effect on the chiral guest molecule bound.

A correction to the article "Bifunctional Porphyrin Catalysts for the Synthesis of Cyclic Carbonates from Epoxides and C02: Structural Optimization and Mechanistic Study" in the September 2014 issue is presented.

The catalytic reactions of indoles with CO 2 and phenylsilane afforded indolo[3,2- b ]carbazoles, where the fused benzene ring was constructed by forming two C-H bonds and four C-C bonds with two CO 2 molecules via deoxygenative conversions. Nine-membered cyclophanes made up of three indoles and three CO 2 molecules were also obtained, where the cyclophane framework was constructed by forming six C-H bonds and six C-C bonds. These multicomponent cascade reactions giving completely different carbocycles were switched simply by choosing the solvent, acetonitrile or ethyl acetate.
