Coupling of diazonium salts with ethyl sulfonylpyruvates 1-3 or arenesulfonylacetic acids 14,15 afforded good yields of the corresponding 1,5-symmetrically disubstituted-3-sulfonylformazans 4-1 1. The new sulfonyl macrocyclic crown formazans 25-32 were prepared by coupling of the appropriate bisdiaz

The enantioselective synthesis of a model of the core ring system of cyathin diterpenes is described. The key tricyclic acetate 4 was assembled via an intramolecular Heck-type cyclization of the chiral triflate 8. Acetate 4 was taken through to model cyathan ketones 3a and 3b by a one-carbon ring ex
