Synthesis of 2,3-seco-triterpene hydrazonohydrazides of the lupane and 19β,28-epoxy-18α-oleanane types

Hydrazonohydrazides were synthesized by acid-catalyzed condensation of 2,3-seco-triterpene 1-cyano-3hydrazides with aldehydes. The antiviral action of the hydrazonohydrazides was studied against vesicular stomatitis Indiana virus.
