In. Houpis et al., TOWARDS THE SYNTHESIS OF HIV-PROTEASE INHIBITORS - SYNTHESIS OF OPTICALLY PURE 3-CARBOXYL-DECAHYDROISOQUINOLINES, Tetrahedron letters, 34(16), 1993, pp. 2593-2596
The synthesis of optically pure decahydroisoquinoline 1, a component o
f HIV-protease inhibitors, was accomplished in 30-33% overall yield fr
om the readily available optically pure monoacid 4.
