An interesting extension of such syntheses is to generate an isotopically labeled non-chiral compound into which chiral center(s) are introduced by an enzymatical method. Thus, [2 R,3 R - 2 H 2 ]heptanoic acid was generated by exposing [2,3- 2 H 2 ]2 E -heptenoic acid to the enoate reductase of Clostridium tyrobutyricum [ 55, 59 ].Cited by: 9. This book reviews the progress in all key areas of natural product chemistry since The most significant advances are highlighted over a wide field of chemistry, structure, synthesis and biosynthesis. This book should be of interest to organic, natural product and synthetic chemists, as well as biotechnologists and biochemists.
