The front cover illustrates the diastereoselective formation of condensed heterocyclic ring systems by domino reaction sequences. dominoes toppling each other represent steps sequences, transformation initiating next one. mechanism cyclization is tunable choice reagent, affording four different systems. A novel mild nitroarenes to N-hydroxyindoles, in which deoxygenation carried out an intramol...

Estudos metabólicos envolvendo a incorporação de D-glicose-[1-13C] em folhas de Piper aduncum (Piperaceae) mostraram que as vias do mevalonato (MVA) e da triose-piruvato (MEP) estão envolvidas na biossíntese da unidade isoprênica presente no 2,2-dimetil-2H-1-cromeno-6carboxilato de metila (1) e no 2,2-dimetil-8-(3’-metil-2’-butenil)-2H-1-cromeno-6-carboxilato de metila (2). O padrão de incorpor...

Multi-component reactions for the construction of heterocycles have been fascinated by microwave energy as an alternative technique heating, owing to advantages over traditional reflux methods. The heterogeneous catalysts contribute significantly towards recycling, harmless, easy filtration, catalyst preparation, more life span, abundance, and product yields. With novel creative uses in organic...
