Studies in the directed cyclopropanation of α-allenic alcohols

Lautens, Mark,Delanghe, Patrick H. M.

, p. 8526 - 8535 (2007/10/02)

A highly regioselective cyclopropanation of α-allenic alcohols using samarium/dihalomethane provides a variety of methylene- and alkylidenecyclopropane carbinols in good yield. The nearby hydroxyl moiety and the samarium reagent are essential for this uni

REACTION OF METHYLENECYCLOPROPYLLITHIUM WITH ELECTROPHILES

Thomas, Edward W.

, p. 1467 - 1470 (2007/10/02)

Metalation of methylenecyclopropane witn n-butyllithium in tetrahydrofuran affords methylenecyclopropyllithium, which reacts with carbonyl electrophiles to produce alcohols in high yields.
