Synthesis and absolute configuration of two defensive alkaloids from the Mexican bean beetle, Epilachna varivestis
Syntheses of (2S,12’R)-2-(12′-aminotridecyl)-pyrrolidine (1) and (28,12’R)-1-(2′-hydroxyethyl)-2-(12′-aminotridecyl)-pyrrolidine (2), two defensive alkaloids recently isolated from the Mexican bean beetle, Epilachna varivestis, are described. By a comparison of 1H NMR data of MTPA derivatives of natural alkaloid 2 with those of the synthetic standard, we confirm the (2S,12’R) configuration previously suggested for this alkaloid. Further support of these assignments was provided by the synthesis and 1H NMR investigation of(2S,12’S)-1, (2S,12’S)-2, and their MTPA derivatives.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 4254-15-3
