The first asymmetric synthesis of mycolipenic acid and mycolipanolicacid by using an improved iterative procedure involving catalytic asymmetric conjugate addition of MeMgBr as the key step is described. Mycolipenic and mycolipanolicacid are obtained in 11 steps with perfect stereocontrol, and both acids are identical to their counterparts from natural sources.

The asymmetricsynthesis of four stereoisomers of DAT2, an important antigen of M. tuberculosis, showed that the commonly accepted structure of DAT2 and its acyl substituent mycolipanolic acid had to be corrected. DAT2 is an effective ligand activating Mincle, an important pattern recognition receptor of the immune system.
