Abstract: A process for the production of an ergot alkaloid comprising intramolecularly cyclizing a 3-iminoethyl-4-trans-buta-1',3'-dienylindole to produce an 8-ergolene and as necessary converting the resultant ergolene into the desired ergot alkaloid.

Abstract: A novel norpatchoulenol synthesis is disclosed. The key step in the synthesis is an intramolecular Diels-Alder condensation of a trisubstituted silyloxy derivative of cyclohexadienone. Novel intermediates, namely trisubstituted silyloxy methanonaphthalenes (Formula V, infra) and trisubstituted silyloxy cyclohexadienes (Formula IV, infra) are prepared.

Abstract: The present invention provides compounds of formula I, ##STR1## wherein R.sub.1 is hydrogen; alkyl of 1 to 5 carbon atoms; cycloalkyl of 5 to 7 carbon atoms; alkyl of 1 to 4 carbon atoms mono-substituted by cycloalkyl of 3 to 7 carbon atoms; phenylalkyl of 7 to 11 carbon atoms in the aggregate thereof, wherein the phenyl ring is unsubstituted or mono-substituted by halogen of atomic number from 9 to 35, alkyl of 1 to 4 carbon atoms; or alkoxy of 1 to 4 carbon atoms; alkenyl of 3 to 5 carbon atoms, wherein the multiple bond is other than in the .alpha.,.beta. position; or 2-hydroxyethyl, andR.sub.2 is hydrogen or alkyl of 1 to 4 carbon atoms,having GABA-like activity.

Abstract: Trans-N-acyl-N-alkyl-1-amino-1,3-butadienes are prepared by contacting a conjugated azomethine with a strong base in an inert organic solvent at sub-zero temperature and thereafter acylating the resulting product. The trans-N-acyl-N-alkyl-1-amino-1,3-butadienes are useful as intermediates in the formation of substituted decahydro-quinolines, Pumiliotoxin C, and can also be used as the diene in Diels-Alder reactions or can be copolymerized with vinyl compounds.
