title: Steric effects of substituents on phenethylamine hallucinogens. 3,4-(Methylenedioxy)amphetamine analogues alkylated on the dioxole ring.
abstract: The compounds 1-(2-methyl-1,3-benzodioxol-5-yl)-2-aminopropane and 1-(2,2-dimethyl-1,3-benzodioxol-5-yl)-2-aminopropane were synthesized and evaluated for pharmacologic effects in mice. These can be viewed as analogues of the known psychotomimetic agent 3,4-(methylenedioxy)amphetamine (MDA). Their hydrochloride salts were compared with MDA for their ability to increase spontaneous motor activity and to elicit behavioral effects. The former compounds was MDA-like in action, while the latter was not. The results suggest that one face of the molecule must be free of steric bulk to possess activity.
