Synthesis of 1′-tetrazolylmethyl-spiro[pyrrolidine-3,3′-oxindoles] via two coupled one-pot processes Ugi-azide/Pictet–Spengler and oxidative spiro-rearrangement
Synthesis of 2-Tetrazolylmethyl-2,3,4,9-tetrahydro-1H-β-carbolines by a One-Pot Ugi-Azide/Pictet–Spengler Process
摘要:
A series of novel 2-tetrazolylmethyl-2,3,4,9-tetrahydro-1H--carbolines were prepared in good to excellent overall yields by an efficient MW-assisted one-pot Ugi-azide/Pictet-Spengler process. This work describes the first synthesis of compounds including both 1,5-disubstituted 1H-tetrazole and 2,3,4,9-tetrahydro-1H--carboline heterocyclic systems.
