A versatile access to new macrocyclic oligoheterocycles (MOH)

An efficient and straightforward methodology for the parallel solid-phase synthesis of a variety of new macrocyclic oligoheterocycles is described. Exhaustive reduction of resin-bound cyclic polyamides using borane generates polyamines. Treatment of separated pairs of amines with a variety of bifunctional reagents provides, following cleavage from the solid support, the desired macrocyclic oligoheterocyclic (MOH) compounds in good yields and purities.
