An "against the rules" double bank shot with diisobutylaluminum hydride to allow triple functionalization of α-cyclodextrin
Abstract
Frustration leads to overreaction: when diametrically opposed regioselective debenzylation is frustrated, an unexpected double debenzylation reaction affords original tetrafunctionalized cyclodextrins in a controlled and efficient manner. A rationale of the reaction is proposed based on a kinetic study.
