Abstract
Highly reactive titanium on graphite as the reagent of choice promotes intramolecular McMurry type reactions of acyloxy-and acylamido carbonyl compounds affording furans, benzofurans and indoles in good to excellent yields. A variety of reducible groups in the substrates is tolerated (eg-F,-Cl,-Br,-I,-CF3,-OMe,-CN,-thiophenyl,-COOR,-CONR2) and strained products such as 11h can be obtained, the X-ray analysis of which is reported. ...
