Abstract

Novel ethenylphenol indoles of the formula ##STR1## wherein R and R.sub.1 are individually selected from the group consisting of hydrogen, alkyl of 1 to 5 carbon atoms, cycloalkyl of 3 to 7 carbon atoms, cycloalkylalkyl of 4 to 7 carbon atoms and aralkyl of 7 to 12 carbon atoms optionally substituted with 1 to 3 members of the group consisting of halogen, methyl, ethyl, methoxy, ethoxy, methylthio, --CF.sub.3, --NH.sub.2 and --NO.sub.2 or R and R.sub.1 together with the nitrogen atom form an optionally unsaturated heterocycle optionally containing a second heteroatom selected from the group consisting of --O--, --S-- and ##STR2## R' is hydrogen or alkyl of 1 to 5 carbon atoms, a together with X is .dbd.0 and b is hydrogen or a together with b is a carbon-carbon bond and X is hydrogen, the dotted line indicates the possibility of a double bond with the compounds having the trans configuration if a double bond, A is selected from the group consisting of ##STR3## and --(CH.sub.2).sub.n --, n is 2,3,4 or 5, R.sub.2 is selected from the group consisting of hydrogen and alkyl of 1 to 5 carbon atoms with the proviso that R and R.sub.1 are not both hydrogen when A is ##STR4## and their non…
