Enantiomeric Natural Products: Occurrence and Biogenesis

Abstract: In Nature, chiral natural products are usually produced in optically pure form; however, on occasion Nature is known to produce enantiomerically opposite metabolites. These enantiomeric natural products can arise in Nature from a single species, or from different genera and/or species. Extensive research has been carried out over the years in an attempt to understand the biogenesis of naturally occurring enantiomers, however, many fascinating puzzles and stereochemical anomalies still remain.

“…[50] Dehydrosecodine has been proposed as an intermediate in the biosynthesis of many indole alkaloid NPs. [51] Therefore, the polyunsaturated structure of dehydrosecodine has preencoded chemical information to build the architectural complexity as well as the scaffold variation of the cognate alkaloids. [51] Thes ynthesis was designed to generate the reactive and oxidation-prone intermediate 73 in situ from ap recursor enyne 72 (Scheme 6).…”

[51] Thes ynthesis was designed to generate the reactive and oxidation-prone intermediate 73 in situ from ap recursor enyne 72 (Scheme 6). Different cyclization and cycloaddition reactions were conducted with this common intermediate,a ffording highly complex NP-like molecules either directly from 73 or in few more steps (Scheme 6).…”

“…Similar phenomenon has also been reported in the insects such as A. chinensis, B. japanensis, and Crotalus molossus. 4,21,36 Because natural compounds are usually enzyme-catalyzed products in the most cases and only a few natural products (<1%) exist as racemic mixtures in nature, 37 why this insect biosynthesizes these racemates is curious.…”
