Abstract
The forest industries are developing new innovative products in addition to the traditional bulk products. A promising raw material for added-value products consists of lignans that are extracted in chemical pulping from residual knots. The anticarcinogenic and antioxidative lignan hydroxymatairesinol (HMR) is found in large amounts in the knots of Norway spruce (Picea abies). It has been used in the synthesis of TADDOL-like α-conidendrin-based chiral 1,4-diols (LIGNOLs) [1] with the same functionality as TADDOLs [5] or BINOLs [2], which are often used as ligands for transition metal catalysed asymmetric synthesis. They have hindered structures containing two adjacent stereocenters, resulting in a fixed angle between the metal-complexing hydroxyl groups.
