A new family of C2/C5 carbon-extended isohexide derivatives is synthesized in a stereo-controlled manner with high purity and good yield. These chiral and rigid biobased building blocks can be widely applied: in pharmaceuticals, cholesteric liquid crystals, and as building blocks for high-performance polymers. The isoidide-based diacid is a potential renewable alternative to terephthalic acid.
