Takahata,Uchida,Momose
, p. 3331 - 3332 (2007/10/02)
An expedient synthesis of homochiral N-protected (R)- and (S)-3-hydroxy-4-pentenylamines (1 and 2) has been accomplished via the enzymatic resolution of the racemic 1 and 2 mediated by immobilized lipase in pentane.

Takahata, Hiroki,Banba, Yasunori,Momose, Takefumi
, p. 7635 - 7644 (2007/10/02)
By starting from the N-alkenylurethane 4, the epoxy urethane ent-5, and the pyrrolidine ent-6 available from the Katsuki-Sharpless kinetic resolution of N-benzyloxycarbonyl-3-hydroxy-1-pentenylamine (2) has been elaborated (-)-supinidine (1). Key Words: K
Asymmetric synthesis of 1-hydroxyindolizidines, biosynthetic precursors to the toxic indolizidine alkaloids slaframine and swainsonine
Takahata,Banba,Momose
, p. 763 - 764 (2007/10/02)
An enantioselective synthesis of 1-hydroxyindolizidines (1 and 2) from racemic N-benzyloxycarbonyl-3-hydroxy-4-pentenylamine (3) by following the Sharpless kinetic resolution, intramolecular amidomercuration, and radical Michael addition as key steps is d
