[structure: see text] A short five-step synthesis of (+/-)-2,2'-bis(diphenylphosphino)-3, 3'-binaphtho[2,1-b]furan (BINAPFu, 1) starting from 2-naphthoxyacetic acid is reported. The resolution of BINAPFu 1 was possible using our newly developed resolution procedure for phosphines wherein (1S)-camphorsulfonyl azide was used to prepare the bisphosphinimine of BINAPFu via the Staundinger reaction. BINAPFu consistently outperformed BINAP in an asymmetric Heck reaction between 2,3-dihydrofuran and phenyl triflate.

2，2'-双（二苯基膦基）-3,3'-双萘并[2,1-b]呋喃的合成，拆分及应用。

[结构：参见正文]从[...]开始的短短五步合成（+/-）-2,2'-双（二苯基膦基）-3，3'-联萘[2,1-b]呋喃（BINAPFu，1）报道了2-萘氧基乙酸。使用我们新开发的膦拆分方法可以拆分BINAPFu 1，其中使用（1S）-樟脑磺酰叠氮化物通过Staundinger反应制备BINAPFu的双膦亚胺。BINAPFu在2,3-二氢呋喃和三氟甲磺酸苯酯之间的不对称Heck反应中始终优于BINAP。
