✦ Synopsis


The convergent total synthesis of (-)-pironetin using a chiral building block, (1S,5S,6R)- 5hydroxybicyclo[4.1.0]heptan-2-one 5 is described. Both the dithiane 4 and the epoxide 2 with proper substituents were employed as coupling partners to construct the whole carbon skeleton 15, which was converted to pironetin 1 in a few steps.
