Reactions of acetylamino substituted 2-allyl-phenols (1 and 2), and 2-methallyl-phenol (6), respectively, with different arylsulfenyl chlorides (3a-d) yield the products of a cyclofunctionalization 5- or 7-acetylamino-2-arylthiomethyl-2,3-dihydrobenzofurans (4a-d) or (5a-d) and 7-acetylamino-2-arylthiomethyl-2-methyl-2,3-dihydrobenzofurans (7a-d).The compounds 7 are the first examples of cyclofunctionalization of 2-methallylphenols by means of sulfur chlorides.The identification of the products was carried out by mass spectrometry, 1H-n.m.r. spectroscopy and elemental analysis.
