Efficient stereodivergent synthesis of erythro- and threo-sphingosines: Unprecedented reversal of the stereochemistry in the addition
Murakami, Teiichi,Furusawa, Kiyotaka
, p. 9257 - 9263 (2002)
A convenient diastereoselective synthesis of D-erythro- and L-threo-sphingosine derivatives is described. L-Serine-derived aldehyde (Garner's aldehyde) (2) was treated with 1-alkenyl-zirconocene chlorides (3) in the presence of ZnBr2 in THF to give the natural erythro-(anti-) isomers with high diastereoselectivity (anti/syn=12-20:1). In contrast, reaction of 2 with 1-alkenyl-ethyl-zinc, prepared from 3 and Et2Zn, in CH2Cl2 gave the unnatural threo-(syn-) isomers predominantly (anti/syn=1:12-15).

, p. 304 - 310 (2012)
A short and efficient synthetic route to four stereoisomeric 3-acetoxycyclopentenylglycine derivatives from l-serine has been developed. The method features a stereoselective conjugate addition and ring-closing metathesis as key steps. Georg Thieme Verlag Stuttgart · New York.
