The synthesis of a single enantiomer of a major α-mycolic acid of M. tuberculosis
摘要:
We report a synthesis of a single enantionner of a mycolic acid from Mycobacterium tuberculosis containing a di-cis-cyclopropane. The method can be simply varied to modify the chain lengths or the absolute stereochemistry of either cyclopropane. (c) 2005 Elsevier Ltd. All fights reserved.

Stereoselective porcine pancreatic lipase-catalysed hydrolyses of monocyclic meso-1,2-diesters provides a flexible and convenient preparative route to chiral hydroxyesters and lactones of asymmetric synthetic value.
((1S,2R)-2-Hexylcycloprop-1-yl)acetic acid has been synthesised from cis-1,2-dihydroxymethylcyclopropane and shown to be identical to cascarillic acid obtained from cascarilla essential oil. (C) 2004 Elsevier Ltd. All rights reserved.

We report the synthesis of single enantiomers of epoxy-mycolic acids containing an alpha-methyl-transalkene or a cis-cyclopropane with structures that match those of major isomers of such molecules present in complex mixtures in Mycobacteria such as Mycobacterium fortuitum or Mycobacterium smegmatis (C) 2014 Elsevier Ltd.
