Molecular iodine mediated cyclization reactions of 2-(1-alkynyl)benzylic alcohols to substituted indenones
摘要:
efficient I-2-mediated approach to the synthesis of disubstituted indenones from readily available 2-alkynylbenzyl alcohols in the presence of H2O has been developed. These results are different from the known iodocyclization reactions in which O-containing heterocycles are obtained. (c) 2012 Elsevier Ltd. All rights reserved.
