Synthesis Of 2-Acyltetrahydro-β-Carbolines By An Intramolecular α-Amidoalkylation Reaction
摘要:
2-Acyltetrahydro-beta-carbolines 7 have been obtained by cyclization of adducts 5 from imines 3 of tryptamine 1 and aldehydes 2 with acyl chlorides 4 as a result of an intramolecular alpha-amidoalkylation reaction in the presence of bases as N,N-dimethylaniline or Et3N.

The two component one-pot hydroformylation/Fischer indole synthesis sequence of 2,5 dihydropyrroles and phenyl hydrazines allows a facile and convenient access to tetrahydro-beta-carbolines in moderate to good yields.
