Total Synthesis of the Proposed Structures of Indole Alkaloids Lyaline and Lyadine

Bennasar, M.-Lluisa,Roca, Tomas,Monerris, Manuel

, p. 752 - 756 (2004)

The harman-1,4-dihydropyridines 1 and 2, which constitute the originally proposed structures for the indole alkaloids lyaline and lyadine, have been synthesized, and their NMR data have been compared with those available for the natural products. Due to the discrepancies in the spectral data, the structures of lyadine and lyaline should be revised.
