Beyond the two-conformer model: boat conformers provide stereoselectivity in S N 1-type glycosylations of manno -type donors
Abstract
While the S N 1 glycosylation reaction mechanism manifold is dominated by addition reactions to half chair oxocarbenium ions we here reveal that mannosyl oxocarbenium ions react on the bottom face of a boat conformer to avoid steric (Pauli) repulsion.
