Regiocontrolled benzannulation of diaryl(gem-dichlorocyclopropyl)methanols for the synthesis of unsymmetrically substituted α-arylnaphthalenes: Application to total synthesis of natural lignan lactones

(Chemical Equation Presented) An efficient synthesis of highly substituted α-arylnaphthalene analogues has been developed utilizing Lewis acid-promoted regiocontrolled benzannulation of aryl(aryl′)-2,2- dichlorocyclopropylmethanols (aryl ≠ aryl′; abbrevia

A NEW ROUTE TO 1-PHENYLNAPHTHALENES BY CYCLOADDITION: A SIMPLE AND SELECTIVE SYNTHESIS OF SOME NAPHTHALENE LIGNAN LACTONES

2-(2-Dithianyl)benzhydrols (2 a-c) undergo facile cycloaddition reaction with maleic anhydride under thermal conditions to give 1-phenyl-naphthalenes (7 a-c) in one step.The naphthalenes (7 a-c) have been converted into the naphthalene lignan lactones, (9 a-c) and (10 a-c).
