  Novel Synthetic Approach to 6,7-Dihydro-5H-imidazo[1,5-a]-pyrazin-8-ones

  摘要：

  [GRAPHICS]A novel route to highly substituted chiral 6,7-dihydro-5H-imidazo[1,5-a]pyrazine-8-ones starting from Meldrum's acid is disclosed. The key features of the methodology are the incorporation of amino esters as a chiral pool and facile mild intramolecular cyclization to form the pyrazine ring. Incorporation of various substituents at different stages of the synthesis from various building block sets makes this methodology readily amenable to parallel synthesis.
