Application of 126456-43-7, In some cases, the catalyzed mechanism may include additional steps. Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. 126456-43-7, Name is (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol,introducing its new discovery.
Synthesis of novel, potent, diol-based HIV-1 protease inhibitors via intermolecular pinacol homocoupling of (2S)-2-benzyloxymethyl-4-phenylbutanal
The synthesis of novel, potent, diol-based HIV-1 protease inhibitors, having phenethyl groups (-CH2CH2Ph) in P1/P1? position is described. An intermolecular pinacol homocoupling of (2S)-2-benzyloxymethyl-4-phenylbutanal 16 was the key step in the synthesis. From this reaction sequence four carba analogues, compounds 8a, 8b, 9a, and 9b, were prepared, having the inverted configuration of one or both of the stereogenic centers carrying the diol hydroxyls as compared to the parent series represented by inhibitors 6 and 7. Inhibitor 8b was found to be a potent inhibitor of HIV-1 protease (PR), showing excellent antiviral activity in the cell-based assay and in the presence of 40% human serum. The absolute stereochemistry of the central diol of the potent inhibitor (8b) was determined from the X-ray crystallographic structure of its complex with HIV-1 PR.
