Abstract
1,152,820. Dibenzopyran derivatives. T. PETRZILKA. 10 May, 1968 [19 May, 1967], No. 22305/68. Heading C2C. Novel dibenzopyran derivatives of the general Formula (I) wherein R is a hydrogen atom or an alkyl group, with the proviso that when R is in the 3-position it does not represent the n-amyl group, are prepared by condensing a resorcinol derivative of the general Formula (II) wherein R is as defined above, in the presence of an acid, e.g. p-toluene sulphonic acid with 1,5,8-menthatriene or with ( + )-cis and/or ( + )-trans-paramenthadien-(2,8).ol.(1). Pharmaceutical compositions which are useful as psychotomimetic agents, sedatives, analgesics and bactericides and containing dibenzopyran derivatives specified above are administered orally or parenterally in association with a compatible pharmaceutical carrier.
