A regio- and stereocontrolled total synthesis of (-)-allosamizoline is described. The key steps for this synthesis are ring-closing metathesis to form the cyclopentene core, halocyclization to afford the oxazoline ring, and finally stereoselective alkene radical addition followed by an alkene isomerization reaction to install the hydroxymethyl group. (-)-Allosamizoline was prepared in a total of 13
