Nucleophile selectivity in the electrophilic cyclization of substrates like 3 has been investigated in the context of efficient chemo- and stereoselective functionalization of 3-hydroxy-2-(2-methylenecyclohexan-1-yl)butyric acids (cf., 6-9) via iodocyclization. In addition, composite nucleophile selectivities for this diastereomeric series were used to probe the reliability of ground-state conformational analysis as an indicator of relative reactivities for the various conformations of 3. The results provide unambiguous evidence for C1′,C2,C3 stereocontrol in these kinetic iodocyclizations.
