Intramolecular cyclization of beta-nitroso-o-quinone methides. A theoretical endoscopy of a potentially useful innate ‘reclusive’ reaction

Oxidatively generated beta-nitroso-o-quinone methides undergo an o- and/or peri-intramolecular cyclization to arene-fused 1,2-oxazoles, 1,2-oxazines or indoles. The reaction, found to be an innate process, has been scrutinized by DFT/B3LYP and MP2 calculations. Due to its rapidity, the process has been termed a ‘reclusive’ one. Competing o-(1,5)- and peri-(1,6)- or (1,5)-cyclizations advance via successive transition states. Activation barriers are drastically lowered in AcOH, probably through H hopping or tunnelling whereas they are barely reduced in other solvents. Aromaticity indices, such as HOMA, IA and ABO, have been used to assess the stability of the end-heterocycles and the preponderance of any one of them. Thus, the preferred cyclization mode, that is, the prevalence or exclusive formation of one of the heterocycles, appears to be oxidant-directed rather than determined by the quinone methide geometry. The question of the peri-cyclization, being a primary or a secondary process, has been tackled.

Synthesis and evaluation of the anti-proliferative and NF-kappaB activities of a library of simplified tylophorine analogs

Tylophorine and many related phenanthropiperidine alkaloids are extraordinarily potent anti-proliferative agents. Despite their impressive anti-cancer activity, clinical development of these alkaloids has been hampered by their poor solubility and neurological side effects. Although it has been suggested that developing polar phenanthropiperidines will mitigate these undesired properties, the lack of practical methods for the synthesis of such analogues has limited this effort. Here, we present a concise synthetic approach to N-substituted phenanthropiperidines, which enabled a systematic investigation of structure-activity relationships at an underexplored region of the tylophorine scaffold. This work suggests that ring E of tylophorine is essential for the anti-proliferative activity of the 6,7,10,11-tetramethoxy-1,2, 3,4-tetrahydrodibenzo[f,h]isoquinoline core scaffold.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.
