A general strategy for construction of a difluoromethyl compound library and its application in synthesis of pseudopeptides bearing a terminal difluoromethyl group
We describe the development of a novel synthesis strategy that uses common reaction conditions to transform a collection of simple building blocks into complex molecules bearing a terminal difluoromethyl group. The core of this approach is the conscious design and synthesis of new difluorinated building blocks whichcontaininactive and reactive groups on each side of the CF2 group. The strategy is
