Studies on the synthesis of cis-4-hydroxy-L-proline
Smith, Jessica A.,Savage, G. Paul,Hutt, Oliver E.
, p. 1509 - 1514 (2012/02/04)
A high yielding practical three-step procedure, which relies on an extractive work-up procedure, has been developed to convert N-phenylsulfonyl- trans-4-hydroxy-l-proline to N-phenylsulfonyl-cis-4-hydroxy-l-proline methyl ester in 82% yield over three steps.
