Ttoward selective synthesis
WebA general route to isopropenyl esters of N-protected amino-acids is reported, by direct addition of Z-N or Boc-N amino-acids to propyne catalysed by ruthenium(II) complexes; it takes place without racemization. The isopropenyl esters are activated towards amines to afford at 20°C the amide derivatives.

WebHerein is reported an investigation towards the stereoselective synthesis of inherently chiral pseudorotaxanes. Chiral ammonium threads were readily prepared in five steps from racemic or enantiopure (M or P) salts of di-n-propyl-1,13-dimethoxyquinacridinium cation. Their self-assembly with DB24C8 or disymmetrically oriented DB24C8F6 rings formed … WebIn particular we are interested in the application of the principles of catalysis toward selective synthesis of biologically active small molecules and potential large-scale …
