Abstract

Constitutional dynamics, self-assembly, and helical-folding control are brought together in the efficient Sc (OTf) 3/microwave-catalyzed transimination of helical oligohydrazone strands, yielding highly diverse dynamic libraries of interconverting constituents through assembly, dissociation, and exchange of components. The transimination-type mechanism of the ScIII-promoted exchange, as well as its regioselectivity, occurring only at the ...
