X=Y–ZH compounds as potential 1,3-dipoles. Part 64: Synthesis of highly substituted conformationally restricted and spiro nitropyrrolidines via Ag(I) catalysed azomethine ylide cycloadditions

Autor: Cecilia Orgaz de la Cierva, Colin A. Kilner, Mohammed A. B. Sarker, Ronald Grigg, H. Ali Dondas

Publikováno v: Tetrahedron. 64:8974-8991

1,3-Dipolar reactions of imines of both acyclic and cyclic α-amino esters with a range of nitroolefins using a combination of AgOAc or Ag2O with NEt3 are described. In most cases the reactions were highly regio- and stereospecific and endo-cycloaddu

XY–ZH compounds as potential 1,3-dipoles. Part 63: Silver catalysed azomethine ylide cycloaddition—the synthesis of spiro homoserine lactone analogues

Autor: Ronald Grigg, Mohammed A. B. Sarker

Publikováno v: Tetrahedron. 62:10332-10343

A range of room temperature 1,3-dipolar cycloaddition reactions of imines of 2-amino-γ-lactone and thiolactone, catalysed by a combination of AgOAc or Ag2O with NEt3 or DBU, are described. The spiro lactones/thiolactones are formed regio- and stereo
