Abstract

Cpds. of formulae (I) and (II): (where R1 is 1-4C alkoxy or benzyloxy R2 is H or halogen R3 is H or acetyle and is a single or double bond), which have a vasodilating action on the arteries and arterioles, are prepd. by reacting didrovaltrate (II) or (II)-contg. extracts or prepns. with hydrohalic acids in alcoholic solns. and opt. subjecting the resulting (I = double bond R2 = halogen R3 = acetyl) to catalytic hydrogenation and/or alkaline saponification of the acetoxy gp.
