A highly enantio- and diastereoselective [4+1] annulation between in situ generated ammonium ylides and o-quinone methides for the synthesis of a variety of 2,3-dihydrobenzofurans has been developed. The key factors controlling the reactivity and stereoselectivity were systematically investigated by experimental and computational means and the energy profiles obtained provide a deeper insight into the mechanistic details of this reaction.

A concise synthesis of 2-(2-hydroxyphenyl)acetonitriles has been developed through reaction of trimethylsilyl cyanide and the o-quinone methides in situ generated from 2-(1-tosylalkyl)phenols under basic conditions. In addition, 2-(2-hydroxyphenyl)acetonitriles could be conveniently transformed to benzofuranones.
A mild method for generation of o-quinone methides under basic conditions. the facile synthesis of trans-2,3-dihydrobenzofurans

, p. 1660 - 1662 (2013/03/14)
A novel and efficient method for the generation of o-quinone methide intermediates was developed from the readily available 2-tosylalkylphenols under the mild basic conditions, and their reactions with sulfur ylides were investigated for the stereoselective synthesis of trans-2,3-dihydrobenzofurans.
