Abstract: New derivatives of 4-homoisotwistane (tricyclo[5.3.1.0(3,8)]undecane) (3), the olefin (8), bromide (4), alcohols (7,9,11, and 14), ketone (10), acid (12), esters (13, 18a, and 18b), amides (5, 16, and 19a-d), nitrile (20), and amines and their hydrochlorides (6, 17, and 21), were prepared, and antiviral activities of these compounds were determined in vitro on a monolayer culture of chick embryo fibroblasts against Newcastle disease virus. 4-Homoisotwist-3-ylamine hydrochloride (6) and 4-homoisotwist-3-ylmethylamine hydrochloride (21) were found 30-50 times more potent than amantadine hydrochloride in this assay. Methods of preparing the test compounds included those functionalization reactions of 3 which revealed many interesting features of the reactivity of the recently discovered polycyclic hydrocarbon 3.
