  Synthetic utility of o-carborane: novel protective group for aldehydes and ketones

  摘要：

  o-Carborane acts as a novel protective group of carbonyl compounds. The reaction of lithiocarborane 2, which was prepared in an essentially quantitative yield from o-carborane and n-butyllithium, with aldehydes or ketones 1 gave the corresponding addition products, o-carboranyl methanol derivatives 3, in high yields. Cleavage of o-carborane from 3 was carried out by treating 3 with catalytic amounts of KOH in THF/H2O (100/1), giving the corresponding aldehydes or ketones in good to high yields along with recovered o-carborane. Accordingly, o-carborane may be utilized as a protective group stable under protic and Lewis acid conditions. Selective alkylation of an ester group, selective reduction of an ester, and selective alkylation of a ketone in the presence of an aldehyde are accomplished by using o-carborane protective groups.
