3-carbonyl-3H-indole: Direct observation and tetramerization to a tetrabenzoporphyrin analogue
摘要:
Heterocyclic ketenes with alpha-nitrogen atoms such as P-carbonyl-PH-indole (6) dimerize to a pyrazinedione type molecule (7). However, the beta-nitrogen analogue, viz. 3-carbonyl-3H-indole (5) oligomerizes to tetramer 4. The direct observation of ketene 5 and the characterization of tetramer 4 are described.

one-pot cascade method for the synthesis of indole-3-carboxylic acids using isatins and DMSO via a one-carbon translocation involving in situ generation of α,β-unsaturated methylvinylsulfoxide followed by amide bond cleavage and ring closure. The methodology has been extended to afford anthranilicacid derivatives by tuning the reaction conditions in the presence of molecular oxygen. Importantly, easy
