Chemoenzymatic Synthesis of Enantiopure 1-Azafagomine
摘要:
A new chemoenzymatic synthesis of both enantiomeric forms of the glycosidase inhibitor 1-azafagomine (1) is reported. The synthesis starts from the achiral starting materials pentadienol and methylurazol with the key steps being a hetero-Diels-Alder reaction followed by a lipase R/Novozym 435-catalyzed enantioselective esterification of the Diels-Alder adduct.
