Polyhydroxylated pyrrolizidines. Part 7. Stereoselective synthesis of unnatural analogs of (+)-casuarine from partially protected DGDP

A new synthetic approach to analogs of (+)-casuarine (2a and 2b), a natural pentahydroxylated pyrrolizidinic alkaloid in a highly stereocontrolled manner, is reported herein. An orthogonally protected polyhydroxylated pyrrolidine, such as (2S,3R,4R,5R)-3,
