  Intramolecular 1,6-hydride transfer in acyclic 1,6-diols: A mechanistic study

  摘要：

  The reaction of acyclic 1,6-diol 11a with 85% phosphoric acid at toluene reflux yields ketone 13a through an intramolecular 1,6-hydride transfer. This fact is proven by using a deuterated 1,6-diol (19), in which the corresponding 1,6-deuteride transfer occurs. A mechanistic proposal through a protonated oxepane (II) is formulated, which implies an actual 1,3-hydride transfer; this mechanism differs from the reported one in the literature for cyclic 1,6-diols, in which a real 1,6-hydride transfer takes place due to a proximity effect.
