Kj. Hale et al., MONAMYCIN SYNTHETIC STUDIES - PT 1 - AN ENANTIOSPECIFIC TOTAL SYNTHESIS OF (3S,5S)-5-HYDROXYPIPERAZIC ACID FROM D-MANNITOL, Tetrahedron letters, 39(39), 1998, pp. 7163-7166
The first enantiospecific total synthesis of (3S,5S)-hydroxypiperazic
acid 1 is described. The synthesis begins from D-mannitol and exploits
a tandem electrophilic hydrazination/nucleophilic cyclisation reactio
n to assemble the hexahydropyridazine ring system. (C) 1998 Elsevier S
