Abstract
Isohexides (isomannide (endo-endo), isosorbide (endo-exo), and isoidide (exo-exo)
are a group of renewable bio-based building blocks that received considerable attention
among the polymer industries because these rigid bicyclic diols have several interesting
properties in polymer applications.1 We are working on more efficient synthetic and
catalytic routes towards isohexide based diamines. The present abstract describes a
dramatically improved synthetic route towards isoidide based diamine.2
An efficient route towards the synthesis of 2,5-diamino-2,5-dideoxy-1,4-3,6-
dianhydroiditol 4 has been developed resulting in significant improvements in both
isolated yields and purity when compared to literature procedures.3,4,5 As a consequence,
resin-grade 2,5-diamino-2,5-dideoxy-1,4-3,6-dianhydroiditol 4 has become available for
laboratory scale step-growth polymer synthesis. Additionally, an interesting renewable
chiral 2-amino-2-deoxy-1,4-3,6-dianhydroiditol 10, has been isolated. These highly
interesting biobased chiral building blocks are presently the subject of several
investigations with regard to high performance bio-based polymers, such as polyamides
and polyurethanes.
