LITHIATED CYCLOPROPANONE KETALS

Dowd, Paul,Kaufman, Christopher,Kaufman, Paul,Paik, Yi Hyon

, p. 2279 - 2282 (2007/10/02)

The ketene acetal I reacted with dibromocarbene yielding the dibromocyclopropanone ketal II, which was reduced to the monobromide III by treatment with tri-n-butyltin hydride.Reaction of III with n-butyllithium at -78 degC yielded the lithiated cyclopropanone ketal IV, which yielded adducts with acetone, cyclohexanone, cyclohexenone, 3,3,3-trimethoxybutan-2-one, and 3-pentanone.
