Total synthesis of (+)-thermozymocidin (myriocin) from D-fructose
Abstract
A total synthesis of thermozymocidin (1) has been achieved using D-fructose as the chiral synthon; the key steps of the synthesis are the transformation of D-fructose into 2-amino-2-deoxy-2-hydroxymethyl-D-mannonic acid (4) and the stereoselective synthesis of the disubstituted (E)-double bond by reaction of the (E)-alkenylcuprate (17) with the tosylate (14).
