Reaction of aryl substituted cis diols with α-acetoxyisobutyryl chloride results in the formation of trans vicinal chlorohydrin acetates where the halide is benzylic. Displacement of chloride with azide ion, deprotection of the ester and reduction of the azide furnishes the requisite cis aminoalcohols. This facile four-step procedure results in the exclusive replacement of a benzylic hydroxyl with

Non-K-region -quinones of polycyclicaromatichydrocarbons are prepared in four steps from cyclic ketones via dehydrogenation of tetrahydrodiols with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone.
