摘要:
A process for the production of .beta.-carboline derivatives of general formula I ##STR1## in which X represents a hydrogen atom or a halogen atom,Y represents a carbon-oxygen bond or a methyl group,R.sub.1 represents an alkyl group with up to 6 carbon atoms andR.sub.2 represents an alkyl group with up to 4 carbon atoms,from 1,2,3,4-tetrahydro-.beta.-carboline derivatives of general formula II ##STR2## in which X, Y, R.sub.1 and R.sub.2 have the above-mentioned meaning, is described, which is characterized in that the 1,2,3,4-tetrahydro-.beta.-carboline derivatives are fermented with a fungi culture of genus Fusarium or Myrothecium.
