  描述：

  O-(2'-hydroxy)ethyl fluorescein (2''-hydroxy)ethyl ester 在 4-二甲氨基吡啶 、 三丁基膦 、 N,N'-二环己基碳二亚胺 作用下， 以 氯仿 为溶剂， 反应 2.0h， 生成 2-({4-[(E)-3-(2-{[(benzyloxy)carbonyl]amino}-3-methoxy-3-oxopropoxy)-2-heptenoyl]benzoyl}oxy)ethyl 2-{6-[2-({4-[(E)-3-(2-{[(benzyloxy)carbonyl]amino}-3-methoxy-3-oxopropoxy)-2-heptenoyl]benzoyl}oxy)ethoxy]-3-oxo-3H-9-xanthenyl}benzoate

  Conjugate addition of amino acid side chains to dyes containing alkynone, alkynoic ester and alkynoic amide linker arms

  摘要：

  Derivatives of fluorescein, 7-hydroxycoumarin, Sudan 1 and dansyl chloride with linker arms containing a conjugated terminal alkyne have been prepared. The Michael addition of the sulfanyl group of protected cysteine, the hydroxyl group of protected serine and the E-amino group of protected lysine to the conjugated alkyne gave the expected heterosubstituted vinyl producs.
