Synthesis of Diverse α-Fluoroalkoxyaryl Derivatives and Their Use for the Generation of Fluorinated Macrocycles.
Introduction of difluorinated functionality has emerged as a powerful means for conformational design with minimal steric footprint. Synthetic approaches for the preparation of aryl difluoromethylene ether containing novel building blocks were established, enabling the inclusion of the aryl difluoromethylene ether system into macrocyclic scaffolds for the first time.
