N. Ikota et al., IMPROVED SYNTHESIS OF 1-DEOXYNOJIRIMYCIN AND FACILE SYNTHESIS OF ITS STEREOISOMERS FROM (S)-PYROGLUTAMIC ACID-DERIVATIVE, Heterocycles, 46, 1997, pp. 637-643
Improved synthesis of 1-deoxynojirimycin (9) from (E)-alpha,beta-unsat
urated ester(1) and facile synthesis of 1-deoxyazasugars (14 and 15) f
rom 10 where both substrates (1 and 10) prepared from (S)-pyroglutamic
acid were described.
