Selective non-nucleoside HIV-1 reverse transcriptase inhibitors. New 2,3-dihydrothiazolo[2,3-a]isoindol-5(9bH)-ones and related compounds with anti-HIV-1 activity
A series of substituted 2,3-dihydrothiazolo[2,3-a]isoindol-5(9bH)-ones and related compounds 1-73 were synthesized and evaluated for their ability to inhibit reverse transcriptase (RT) of the human immune deficiency virus 1 (HIV-1) and replication of HIV-1 in MT2 cells. The antiviral activity of these compounds depends on the stereoselective configuration of the substituent in position 9b. Structure-activity

2-N-hydroxy-1-oxo-3-carboxylic acid of isoquinolone was designed as pyrophosphatemimic for hepatitis C NS5B polymerase. Various 2-hydroxy-1-oxo-1,2-dihydroisoquinoline-3-carboxylic acid derivatives 11a-p were synthesized and evaluated as HCV NS5B polymerase inhibitors. Compound 11c exhibited moderate inhibitory potency based on the inorganic pyrophosphate generation (IC₅₀ = 9.5 μM) and based on NTP incorporation

Pass the baton: A one‐pot relay catalysis for a carbonylylide formation/enantioselective reduction sequence using a dirhodium(II) tetracarboxylate and chiral phosphoric acid catalystsystem is described. The four‐step transformation involves a rhodium carbene complex, a carbonylylide, and an isobenzopyrylium intermediate, the enantioselective reduction of which yields isochromanone derivatives in
