Three approaches have been made towards synthesis of the new norneolignan 2-(2'-hydroxy-4'-methoxyphenyl)-5- benzofuran (1) and successful synthesis of the benzyl ether of 1 has been accomplished using substituted copper (I) acetylide 22 and appropriate o-halophenol 26.
Natural Benzofurans: Synthesis of the Arylbenzofuran Constituents of Sophora tomentosa
McKittrick, Brian A.,Scannell, Ralph T.,Stevenson, Robert
, p. 3017 - 3020 (2007/10/02)
The structure, 2-(2',4-dihydrophenyl)-5,6-methylenedioxybenzofuran (1), suggested for Sophora compound I has been confirmed by a synthesis in which the benzofuran heterocycle was constructed by an intramolecular Wittig reaction of an o-bromomethylphenyl a
A convenient synthesis of 1-bromoolefins and acetylenes by a chain extension of aldehydes

Aldehydes are easily converted to 1-bromoolefins or terminal acetylenes by the use of Wittig reaction of bromomethylenetriphenylphosphorane which is prepared from bromomethyltriphenylphosphonium bromide with potassium tert-butoxide.
