[GRAPHICS]
Effective synthetic uses of bisdiazocarbonyl compounds for the selective co
nstruction of diverse macrocycles, including the synthesis of patulolides A
and a, by catalytic "carbene dimer" formation are reported. Control of ste
reochemistry and efficient methods for product isomerization or kinetic iso
mer differentiation have been achieved.
