One-pot total synthesis: the first total synthesis of chiral alkaloid pimprinol A and the facile construction of its natural congeners from amino acids
In this work, we accomplished the first total synthesis of chiral alkaloid pimprinol A and the facile construction of its natural congeners: pimprinine, pimprinethine, pimprinaphine, WS-30581A, WS-30581B, laboradorin 1, uguenenazole, balsoxine, texamine in one-potfrom commercially available starting materials including amino acids. Further investigating into the mechanism revealed that this improved
A novel, concise, and convenient synthesis of 5‐(3′‐indolyl)oxazoles using relatively benign reagent [hydroxy(2,4‐dinitrobenzenesulfonyloxy)iodo]benezene has been described. The advantages of this procedure include operational simplicity, good yield, and avoidance of the use of toxic metal. J. Heterocyclic Chem., (2010).
