Graphical Abstract

My hat, it has three corners: Enantiopure C3-symmetric triangular macrocycles were synthesized by means of triple asymmetric cyclopropanation. This method is successfully extended to the synthesis of an enantiopure hydrocarbon, which owes its chirality to asymmetric distribution of H/D atoms on the benzene rings.

Abstract

An asymmetric synthesis of C3-symmetric triangular macrocycles is reported. 1-Methylsulfonyl-4-(4-vinylphenyl)-1,2,3-triazole undergoes a rhodium(II)-catalyzed cyclotrimerization to establish an enantiopure C3-symmetric triangular macrocycle motif. This method can be applied to the synthesis of an enantiopure hydrocarbon, which owes its chirality to asymmetric distribution of H/D atoms on the benzene rings.
