Stereoselective synthesis of statin analogues
Bernardi,Micheli,Potenza,Scolastico,Villa
, p. 4949 - 4952 (2007/10/02)
Statin analogues can be synthesized stereoselectively (diastereomeric ratios up to 4:1) starting from malic acid. The key step involves an unprecedented cis-selective allylation of an α-alkoxy N-acyliminium ion.
