The Diels-Alder cycloaddition of the 3,3',4,4'-tetrahydro-1,1'-binapht
halene with 1,4-benzoquinone and N-phenylmaleimide has been studied. T
he one-pot synthesis of the pentahelicenebenzoquinone is reported and
structure analysis of the reaction products by H-1- and C-13-NMR spect
roscopy is presented. (C) 1997 Elsevier Science Ltd.
