Highly Stereoselective Synthesis of cis-(2R,3S)-3-Hydroxyproline
Jurczak, Janusz,Prokopowicz, Piotr,Golebiowski, Adam
, p. 7107 - 7110 (2007/10/02)
Allyltrimethylsilane (5) reacted with N-carbobenzoxy-O-tert-butyldimethylsilyl-L-serinal (4) to give with high diastereoselectivity syn-adduct 3 which was subsequently transformed into cis-(2R,3S)-3-hydroxyproline (1).
