Intramolecular Conjugate Addition of Alkenyl and Aryl Functions to Enones Initiated by Lithium−Iodine Exchange
摘要:
[GRAPHICS]Treatment of each of the substrates 20-26, 29, and 46-48 with t-BuLi in THF, in the presence of HMPA and TMSCl, provides good-to-excel lent yields of the intramolecular conjugate addition products 30-36, 37, and 49-51, respectively.
