An efficient pinacol rearrangement mediated by trialkyl orthoformate has been developed. The reactions of various types of diols with a catalytic amount of a Lewis acid in the presence of an orthoester afforded the rearranged product in good yields via a cyclic orthoester intermediate. This combined system is applicable not only to cyclic and acyclic tri- and tetra- substituted diols but also to the diols having acid-sensitive acetals.

Renewable high-density spiro-fuels are synthesized from lignocellulose-derived cyclic ketones for the first time, which show higher density, higher neat heat of combustion and lower freezing point compared with other biofuels synthesized from the same feedstock, and thus represent a new type of renewable high-density fuel attractive for practical applications.

Three unsymmetrical intercyclic olefins, their dibromides, and their pinacols were prepared, each so the two carbons involved at the functional group were part of a different sized ring. The pinacols were reacted with 25% sulfuric acid and with boron trif
