Lewis Acid - Mediated Addition of Lithiated Alkyl Phenyl Sulphones and Oxiranes. A Method for Synthesis of α,β-Unsaturated Ketones
Marczak, S.,Wicha, J.
, p. 1511 - 1520 (2007/10/02)
Efficiency of the reaction of lithiated alkyl aryl sulphones (1-4) with oxiranes (5, 6) is increased by the presence of BF3 or CeCl3.The respective adducts (7-14) were transformed into α,β-unsaturated ketones (15-22) with high yields.
