General description
1-Octyn-3-ol is a racemic intermediate formed during the synthesis of enantiomerically pure secondary alcohols with sterically similar substituents.
Application
1-Octyn-3-ol was used in the synthesis of synthetic tricolorin A, a novel tetrasaccharide macrolactone that is a natural herbicide†.

A novel chemoenzymatic strategy for the synthesis of enantiomerically pure secondary alcohols with sterically similar substituents is described. The key step is the kinetic lipase-catalyzed resolution of racemic mixtures of substituted propargylic alcohols. The efficiency of this new approach was
