[Betulonic amides modified at the ring A by amino acids: synthesis and inhibition of influenza A virus reproduction].
The Beckman rearrangement of carboxy- and alkyloxycarbonylalkylamides of 3-hydroxyiminobetulonic acid led to derivatives of 3a-homo-4-aza-3-oxolup-20(29)-ene and 3,4-seco-2-cyanolupa-4(23),20(29)-diene. An X-ray analysis showed methyl 3-(N-acetoximino)lup-20(29)-enoate is the E-isomer. The compounds synthesized exhibited inhibiting activity toward the reproduction of flu A virus in cell culture.
