[reaction: see text] A convergent and concise route to an advanced precursor 2b of kendomycin (1) has been developed by applying a S(N)1 ring cyclization as a key step. The resulting C-aryl glycoside was initially isolated as a rotameric mixture, but after MOM protection of the o-hydroxyl of the phenol, the conformation was frozen to the desired kendomycin-like atropisomer.
