β¦ Synopsis
Rrefeldin A (9 is a macrocyclic fungal metabolite which exhibits both antibiotic and antiviral activity.
A route for the total synthesis of this substance in racemic form has recently been established and reported from these laboratories. ' This note describes modifications in the synthetic sequence which have allowed a shorter and more efficient synthesis. The methods used in these modifications are expected to be generally
