A Synthesis of the Diazonamide Heteroaromatic Biaryl Macrocycle/Hemiaminal Core

(Matrix presented) Stille coupling of an arylstannane aminal 19 with the palladium complex 23 leads to atropisomeric esters 28 and 29. Conversion to macrocycle 30 is demonstrated, a potential precursor of natural and unnatural diazonamides.
