  Asymmetric synthesis of (3S,4R,5R)-4,5-dihydroxy-3-methyl-2,3,4,5-tetrahydropyridazine: a formal synthesis of 1-azagulofagomine analogues

  摘要：

  The stereoselective synthesis of (3S,4R,5R)-4,5-dihydroxy-3-methyl-2,3,4,5-tetrahydropyridazine from [(S)R]-(1E,3E)-1-p-tolylsulfinyl-1,3-pentadiene is reported. The domino reaction of the 1-sulfinyldiene with 1,2,4-triazoline-3,5-dione (a hetero Diels-Alder, sulfoxide-sulfenate rearrangement, and sulfenate hydrolysis), eis-dihydroxylation of the resulting alkene and hydrazinolysis with elimination of a N-methylurazol residue are the key steps of the sequence.
