Area of Science:

• Organic Chemistry
• Supramolecular Chemistry
• Stereochemistry

Background:

• Chiral macrocycles with multiple chirality are vital for physical and biological applications.
• Inducing multiple chirality during macrocyclization is a significant synthetic challenge.

Purpose of the Study:

• To explore and establish a novel method for inducing multiple chirality in macrocyclization reactions.
• To achieve excellent stereoselectivity in the synthesis of complex chiral macrocycles.

Main Methods:

• Utilized self-assembled, single-layer chiral porous sheets formed by planar aromatic amphiphiles.
• Employed confined macrocyclization within these chiral porous structures.
• Leveraged the chiral environment to control substrate conformation and stereochemical outcomes.

Main Results:
