A base-mediated three-component coupling reaction for the synthesis of phosphorohydrazones
摘要:
A simple and efficient three-component coupling reaction for the synthesis of phosphorohydrazones was developed. Both aldehydes and ketones participated in the reaction to afford the corresponding phosphorohydrazones in moderate-to-good yields. Moreover, a novel P-N ligand was synthesized by this method, which can act as a fluorescent sensor for iron ion. (C) 2013 Elsevier Ltd. All rights reserved.

The paper presents a simple synthesis of substitutedpropargyl vinyl ethers and their subsequent thermally-initiated Claisen rearrangement leading to various 3-substituted homoallenyl aldehydes. Several methods, including Sonogashira coupling, base-promoted substitution on the triple bond by sodium amide or butyllithium, and the preparation of substitutedpropargyl alcohols, were used in the initial
