Stereoselective Z-iodoalkoxylation of 1,2-allenyl sulfides or selenides
摘要:
Iodoalkylation of 1,2-allenyl sulfides or selenides with 1(2) in MeCN/ROH (20: 1) afforded Z-3-alkoxy-2-iodopropeny) sulfides or selenides in high stereoselectivity and moderate to Pod yields. The carbon-iodine bonds in these compounds may undergo Suzuki, Negishi, and Sonogashira coupling reaction smoothly. (c) 2005 Elsevier Ltd. All rights reserved.
