Gunnarsson, Kerstin,Ragnarsson, Ulf
, p. 944 - 951 (2007/10/02)
The synthesis of Nα-di-tert-butoxycarbonyl amino acids starting from the corresponding mono-derivatives via a three-step route is reported.The latter were converted into a suitable ester and then exhaustively t-butoxycarbonylated, after which t
9-FLUORENYLMETHYL ESTERS AS CARBOXYL PROTECTING GROUP
Kessler, Horst,Siegmeier, Rainer
, p. 281 - 282 (2007/10/02)
The use of 9-fluorenylmethyl esters for the protection of carboxyl groups is proposed.The advantage of this group is the selective deprotection under mild conditions using secondary amines without racemization.
