  THE DDQ MEDIATED CYCLIZATION PRODUCTS OF SOME 2-HYDROXY-3-(1?-ALKENYL)-1,4-NAPHTHOQUINONES

  摘要：

  The DDQ mediated cyclisation products derived from 2-hydroxy-3-(1'-alkenyl)-1,4-napthoquinones viz. (17) under bar were found to be temperature dependent. At 60degreesC the naphthofuranquinone (19) under bar was the predominant isomer whereas at 8degreesC, the naphthopyranquinone (18) under bar was exclusively formed.
