A new synthesis of phenanthridine derivatives having three-point diversity has been developed based on the sequential application of three-atom economic processes viz. aza-Claisen rearrangement, ring-closing enyne metathesis and Diels-Alder reaction as key steps. An unexpected isomerisation was observed during aza-Claisen rearrangement of N-allylanilines which may open up new opportunities in heterocyclic synthesis.
Synthesis of indolines, indoles, and benzopyrrolizidinones from simple aryl azides

A simple approach to prepare indolines and benzopyrrolizidinones from ortho-azidoallylbenzenes via a tandem radical addition/cyclization is described. The use of triethylborane to initiate and sustain the process provides the best results. Indolines are easily converted into the corresponding indoles by oxidation with manganese dioxide.
Pd(II)-catalyzed enantioselective oxidative tandem cyclization reactions. Synthesis of indolines through C-N and C-C bond formation
Yip, Kai-Tai,Yang, Min,Law, Ka-Lun,Zhu, Nian-Yong,Yang, Dan
, p. 3130 - 3131 (2007/10/03)
We have developed an efficient Pd(II)-catalyzed enantioselective oxidative tandem cyclization strategy using molecular oxygen as a green oxidant for the double 5-exo-trig cyclizations of N-(2-allylaryl) amides to afford a variety of indolines in good yiel
Asymmetric carbon-carbon bond formations in conjugate additions of lithiated N-Boc allylic and benzylic amines to nitroalkenes: Enantioselective synthesis of substituted piperidines, pyrrolidines, and pyrimidinones
Johnson, Timothy A.,Jang, Doo Ok,Slafer, Brian W.,Curtis, Michael D.,Beak, Peter
, p. 11689 - 11698 (2007/10/03)
(-)-Sparteine mediated lithiations of N-Boc-allylic and benzylic amines provide configurationally stable intermediates which on conjugate additions to nitroalkenes provide highly enantioenriched enecarbamate products in good yields, and with high diastere
