Total synthesis of uniflorine A, casuarine, australine, 3-epi-australine, and 3,7-di-epi-australine from a common precursor

(Chemical Equation Presented) Aflexible method for the diastereoselective total synthesis of the pyrrolizidine alkaloids uniflorine A, casuarine, australine, and 3-epi-australine and the unnatural epimer 3,7-di-epi-australine from a common chiral 2,5-dihydropyrrole precursor is described. 2009 American Chemical Society.

Synthesis of Putative Uniflorine A

A diastereoselective synthesis of the putative structure of the natural product uniflorine A has been achieved by using the Petasis borono-Mannich reaction and ring-closing metathesis as key steps. The NMR data of the synthetic material did not match that
