G. Casiraghi et al., BUTOXYCARBONYL-2-(TERT-BUTYLDIMETHYLSILOXY)PYRROLE AS A GLYCINE ANIONEQUIVALENT - A FLEXIBLE ENANTIOSELECTIVE ACCESS TO POLYHYDROXY-ALPHA-AMINO ACIDS, Tetrahedron letters, 35(15), 1994, pp. 2423-2426
An efficient stereoselective route to polyhydroxy-alpha-amino acids 7a
-f was developed by exploiting butoxycarbonyl-2-(tert-butyldimethylsil
oxy)pyrrole as a glycine anion equivalent.
