An alkylation/cyclization sequence, with both steps mediated by the ortho-N-methylformamido-phenylsulfinyl function, provided two new C-C bonds and an efficient entry to 1-aryl-tetralins and 4-aryl-benzopyrans. Scope and limits of the process have been studied in detail. (c) 2005 Elsevier Ltdv. All rights reserved.

The BF3 catalysed cyclisation of 3-arylpropyl substituted quinone-methide ketals affords a mild, biomimetic route to aryltetralins. 1H- and 13C-NMR spectra of the products are reported.
