A new strategy for the synthesis of chromans and chromenes
摘要:
Sonogashira coupling of 7-iodobenzotriazole derivative 9 with propargylic alcohols followed by alkyne reduction leads to alkanols 11 or alkanols 12 which cyclize upon benzyne generation to give the iodo-chromanes 14 and iodo-chromenes 16. (C) 1998 Elsevier Science Ltd. All rights reserved.
