Synthesis of Homochiral R-Baclofen from S-Glutamic Acid
Herdeis, C.,Hubmann, H. P.
, p. 1213 - 1221 (2007/10/02)
A streoselective synthesis of R-Baclofen is presented starting from S-pyroglutamic acid derivative 3.The key steps are the 1,4-conjugate addition of Grignard cuprate (p-ClPh)2CuMgCl to 3 and Barton-Decarboxylation of 6e to 7e.
