Asymmetrized tris(hydroxymethyl)methane (THYM*) is a new chiral building block easily accessible in both enantiomeric forms by a chemoenzymatic methodology. The presence of three synthetically equivalent masked hydroxymethyl groups and a high degree of latent symmetry (C3v) makes this synthon very versatile in synthetic applications. This review describes its preparation and a series of elaborations (with particular enphasis on the diastereoselective generation of additional chiral centers) leading to advanced intermediated for the preparation of biologically active compounds.

Abstract
Asymmetrized tris(hydroxymethyl)methane (THYM*) is a new chiral building block easily accessible in both enantiomeric forms by a chemoenzymatic methodology. The presence of three synthetically equivalent masked hydroxymethyl groups and a high degree of latent symmetry (C3v) makes this synthon very versatile in synthetic applications. This review describes its preparation and a series of elaborations (with particular enphasis on the diastereoselective generation of additional chiral centers) leading to advanced intermediated for the preparation of biologically active compounds.
