Reduction of ortho-Quinones to Dihydrodiols
Kundu, Nitya G.
, p. 1920 - 1923 (2007/10/02)
1,2-Naphthaquinone, 5-bromo-1,2-naphthaquinone and dibenzanthracene-3,4-quinone in the form of dibromo-intermediates were reduced to a mixture of cis- and trans-diols by the action of sodium borohydride in ethanol.An alternative synthesis of trans-3,4-dihydroxy-3,4-dihydrodibenzanthracene is also reported.
