A first example of simple and efficient hydrophilic Pd-phosphine complexes catalyzed one-pot three-component reaction of ortho-bromo aldehydes, terminal alkynes and ammonium acetate proceeds through the tandem coupling-imination-annulation path for the synthesis of substituted isoquinolines, furopyridines and thienopyridines in good to excellent yields in green aqueous medium at mild temperature was described. 相似文献

The efficient and simple stereoselective approach toward the total synthesis of simplactone A is described. The key features of this synthetic strategy include stereoselective C-ethylation, selective triol protection, and Wittig olefination for the formation of the six-membered ring. 相似文献
