Multicomponent Assembly of Organoboron Compounds Efficient Approach to Supramolecular Chemistry

43 MULTICOMPONENT ASSEMBLY OF ORGANOBORON COMPOUNDS EFFICIENT APPROACH TO SUPRAMOLECULAR CHEMISTRY 

In this section, interesting synthetic strategies for the construction of boron-based macrocycles and dendrimers [7] are described, as appealing building blocks for applications as sensors [8], catalysts, nanoarchitectures [9], separation, and delivery [10]. 

In this field, great achievements have been reported by the group of Severin and coworkers who have focused part of their research on the development of this new area, and they have reached interesting results that will be summarized here. 

SCHEME 4.3 Four-component one-pot reaction via two cobalt-catalyzed 1,4-hydrovinylations and allylboration. dppp, 1,2-bis(diphenylphosphino)propane. 

SCHEME 4.4 Five-component one-pot reaction via triple-cobalt-catalyzed reaction sequences, py-imine, 2,4,6-trimethylphenyl-A -(pyridin-2-ylmethylene)aniline.
