Regio- and stereoselective copper-induced isomerization of 2-alkenyl 2-lithiophenyl ethers to 2-(2-alkenyl)phenols
摘要:
N-Allyl-N-(2-lithioallyl)aniline undergoes intramolecular carbometallation via 5-exo addition on treatment with CuCN. 2-Alkenyl 2-bromophenyl ethers rearrange to 2-(2-alkenyl)phenols by bromine-lithium exchange and further transmetallation with CuCN. (C) 1997 Elsevier Science Ltd.

Alkylation of aluminum phenolate by nerol and of phenol by nerol in the presence of the organoaluminum compounds aluminum phenolate and aluminumisopropylate was studied. The reaction products were isolated and characterized. Several features of the process were determined. It was found that ortho-substitution of the aromatic ring occurred primarily. In several instances nerol was cyclized. The fraction
