Diels-Alder reaction of 3,3′,4,4′-tetrahydro-1,1′-binaphthalene. One-pot synthesis of a pentahelicenebenzoquinone
摘要:
The Diels-Alder cycloaddition of the 3,3',4,4'-tetrahydro-1,1'-binaphthalene with 1,4-benzoquinone and N-phenylmaleimide has been studied. The one-pot synthesis of the pentahelicenebenzoquinone is reported and structure analysis of the reaction products by H-1- and C-13-NMR spectroscopy is presented. (C) 1997 Elsevier Science Ltd.
