  Chiral Aminophosphines as Catalysts for Enantioselective Double-Michael Indoline Syntheses

  摘要：

  双膦催化的二核亲核试剂对缺电子乙炔的双Michael加成反应是合成多种含氮杂环的高效过程。由于生成的杂环至少含有一个立体中心，如能开发出该反应的不对称变体，双Michael反应将更加有用。氨基膦也可促进双Michael反应，而天然及合成中手性胺更易获得；因此，本研究中我们制备了几种新型手性氨基膦。在甲苯磺酰胺基苯基丙二酸酯与3-丁炔-2-酮的不对称双Michael反应中，手性氨基膦以良好产率制得吲哚啉，并具有中等程度的手性诱导作用。

  Seven different types of benzannulated N-heterocycles-indolines, dihydropyrrolopyridines, benzimidazolines, dihydrobenzo-3,1-oxazines, benzomorpholines, tetrahydroquinolines, and tetrahydroisoquinolines-can be obtained from simple dinucleophiles and electron-deficient acetylenes in one synthetic step. This powerful methodology was made possible through the use of diphenylphosphinopropane (DPPP) as the catalyst, with acetic acid and sodium acetate used as additives in some cases. The benzannulated N-heterocycles were isolated in excellent yields under mild metal-free conditions; they were purified without the need for aqueous workups.

  The bisphosphine-catalyzed double-Michael addition of dinucleophiles to electron-deficient acetylenes is an efficient process for the synthesis of many nitrogen-containing heterocycles. Because the resulting heterocycles contain at least one stereogenic center, this double-Michael reaction would be even more useful if an asymmetric variant of the reaction were to be developed. Aminophosphines can also facilitate the double-Michael reaction and chiral amines are more readily available in Nature and synthetically; therefore, in this study we prepared several new chiral aminophosphines. When employed in the asymmetric double-Michael reaction between ortho-tosylamidophenyl malonate and 3-butyn-2-one, the chiral aminophosphines produced indolines in excellent yields with moderate asymmetric induction.
