Asymmetric sulfur ylide based enantioselective synthesis of D-erythro-sphingosine
Morales-Serna, Jose Antonio,Llaveria, Josep,Diaz, Yolanda,Matheu, M. Isabel,Castillon, Sergio
, p. 4502 - 4504 (2008)
An asymmetric sulfur ylide reaction was employed to prepare an epoxide intermediate in a convergent manner. This epoxide was efficiently transformed into D-erythro-sphingosine.
