Asymmetric synthesis of optically active decahydroisoquinolines useful in HIV-1 protease inhibitor synthesis
摘要:
An efficient synthesis of amino acid ester 8 is described featuring an asymmetric aza-Diels-Alder reaction of diene 5 and chiral imine 6 which establishes the asymmetry at C-3. Hydrogenation of 7 provides 8 with the desired asymmetry at C-4a and C-8a.
Towards the synthesis of HIV-protease inhibitors. Synthesis optically pure 3-carboxyl-decahydroisoquinolines.
摘要:
The synthesis of optically pure decahydroisoquinoline 1, a component of HIV-protease inhibitors, was accomplished in 30-33% overall yield from the readily available optically pure monoacid 4.
