  Synthetic applications of bis(iminophosphoranes). One-pot preparation of rigid bicyclic guanidines

  摘要：

  A one-pot synthesis of [6 + 6], [6 + 7], and [6 + 8] bicyclic guanidines based on a new method of dihydropyrimido annelation, which involves reaction of bis(iminophosphoranes) with aryl isocyanates or isothiocyanates is described. The method is also applicable for the preparation of chiral bicyclic guanidines.

  efficient one-pot and regioselective synthesis of 3,4-dihydroquinazolines and 4,5-dihydro-3H-1,4-benzodiazepin-3-ones by Ugi/Staudinger/aza-Wittig sequence has been developed. The Ugi reactions of 2-azidobenzylamines, aldehydes, acids (or α-keto acids) and isocyanides produced the azide intermediates, which were then treated with tributylphosphine or triphenylphosphine to give polysubstituted 3,4-dihydroquinazolines

  已经开发了通过Ugi / Staudinger / aza-Wittig序列有效地一锅法和区域选择性合成3,4-二氢喹唑啉和4,5-二氢-3 H -1,4-苯并二氮杂-3-酮的方法。2-叠氮基苄胺，醛，酸（或α-酮酸）和异氰酸酯的Ugi反应生成叠氮化物中间体，然后将其用三丁基膦或三苯基膦处理，得到多取代的3,4-二氢喹唑啉或4,5-二氢-3 H通过串联Stander / Aza-Wittig反应，中度至良好产率的-1,4-苯并二氮杂-3-酮。

  new one-pot and regioselective synthesis of 3,4-dihydroquinazolines by Ugi/Staudinger/aza-Wittig sequence has been developed. The Ugi-type reaction of 2-azidobenzylisocyanide, aldehyde, secondary amine and acid produced an azide intermediate, which was then treated with triphenylphosphine to give 3,4-dihydroquinazolines regioselectively in good overall yields by Staudinger/aza-Wittig reaction at room
