Synthetic spiro[pyrrolidine-2,2'-adamantanes] 2, 3, 11, 15, 12, 16, 18, 20 were evaluated in vitro and found to be active anti-influenza virus A compounds; the effect of the position of C-Me pyrrolidine ring substituent on antiviralactivity was examined. Pyrrolidine 5-Me substitution appears to be optimal for H(2)N(2) strain activity. From the four different possible protonated conformers, experimental
