Derivatives of 2,3,4,5-tetrahydro-1H-pyrido[4,3-b]-indole and of (+)enantiomeric, mixtures of (+) and (-)enantiomeric or (.+-.)racemic 2,3,4,4a,5,9b-hexahydro-4a,9b-trans-1H-pyrido[4,3-b]indole, substituted at the 5-position with an aryl group and at the 2-position with a carbonylaminoalkyl group or an aminoalkyl group, are neuroleptic agents useful in the treatment of certain psychoses and neuroses.
An unexpected homologation/dyotropic rearrangement/interconversion/[3+2] cycloaddition cascade reaction of α‐diazoester‐terminated N‐propyl‐substituted isatin derivatives was achieved in the presence of a chiral N,N′‐dioxide/ScIII catalyst. This catalytic manifold allows rapid construction of several classes of dimeric polycyclic compounds with good yields and high levels of diastereo‐ and enantioselectivity
