The construction of diverse sp3-rich skeletal ring systems is of importance to drug discovery programmes and natural product synthesis. Herein, we report the photocatalytic construction of 2,7-diazabicyclo[3.2.1]octanes (bridged 1,3-diazepanes) via a reductive diversion of the Minisci reaction. The fused tricyclic product is proposed to form via radical addition to the C4 position of 4-substituted quinoline substrates, with subsequent Hantzsch ester-promoted reduction to a dihydropyridine intermediate which undergoes in situ two-electron ring closure to form the bridged diazepane architecture. A wide scope of N-arylimine and quinoline derivatives was demonstrated and good efficiency was observed in the construction of sterically congested all-carbon quaternary centers. Computational and experimental mechanistic studies provided insights into the reaction mechanism and observed regioselectivity/diastereoselectivity.

The one-pot synthesis of 2-arylquinoline with arylamines, arylaldehyde, and 1,1-diethoxyethane were studied using a catalytic amount ytterbium triflate. Various 2-arylquinolines showed fluorescence properties and the fluorescence was quenched by introduci
Pot, atom, and step economic (PASE) synthesis of highly substituted piperidines: A five-component condensation
Clarke, Paul A.,Zaytsev, Andrey V.,Whitwood, Adrian C.
experimental part, p. 3530 - 3532 (2009/05/26)
The diastereoselective pot, atom, and step economic (PASE) synthesis of highly functionalized piperidines is reported. The procedure simply involves mixing methyl acetoacetate, two equivalents of aldehyde and two equivalents of aniline together in the presence of indium(III) chloride. In most cases the piperidine precipitates out of solution. Georg Thieme Verlag Stuttgart.
