Extension of β-chloroenals to ethyl 5-chloro-2,4-pentadienoates using Wadsworth–Emmons reactions: subsequent conversions to 5-aryl-5-chloro-2,4-pentadienoic acids and 5-aryl-2-penten-4-ynoic acids
摘要:
Convenient routes from (Z)-3-aryl-3-chloroenals to (2E,4Z)-5-aryl-5-chloro-2,4-pentadienoates and (2E)-5-aryl-2-penten-4-ynoates are described. The stereochemical assignments are based on NMR spectral data. (C) 2004 Elsevier Ltd. All rights reserved.
