Syntheses of the plant auxin conjugate 2-O-(indole-3-acetyl)-myo-inositol IAInos

Org Biomol Chem. 2018 Oct 3;16(38):6860-6864. doi: 10.1039/c8ob02096e.

Abstract

The plant hormone conjugate 2-O-(indole-3-acetyl)-myo-inositol (IAInos) has been selectively prepared for the first time by two routes from myo-inositol. One of the syntheses depended upon the construction of the 3-indoleacetyl group by a Fischer indole synthesis on an unreactive axial hydroxyl group, while the other via a direct acylation of the equatorially orientated hydroxy group created by conformational constraint of the cyclohexane ring. The latter synthesis produced IAInos in 5 steps and 29% overall yield.
