ABSTRACT
The mechanical bond is emerging as a novel design element in catalyst development. Here, we report a series of 1,1'-binaphthyl-2,2'-diol (BINOL) based catalysts in which the number of interlocked macrocycles is varied. Unsurprisingly, the macrocycles have a profound steric influence on the catalytic performance of these molecules. However, in the enantioselective transformations examined, the macrocycles are detrimental to catalyst stereoselectivity whereas in lactide polymerization, they increase the molecular weight of the polymeric product.
