The formation of oxa-tricyclic core of platensimycin was attempted. A key precursor of radical cyclization, cyclic anhydride, was readily prepared from diethylmalonate in 6 steps in good yields. Obtained precursor, diallylmethylene-δ-lactone, underwent radical cascade reaction triggered by thiyl radical, giving bicyclic ether in a stereoselective manner.

Enantiomerically pure chiral crown ethers containing the phenazine unit [(R,R)-2-(S,S)-8] were prepared by two types of cyclization reactions. Ligands (R,R)-2, (R,R)-3, (S,S)-4, (R,R)-5, (R,R)-6 and (R,R)-7 were prepared from phenazine-1,9-diol 9 and the
