Palladium-catalyzed intramolecular C-O bond formation: An approach to the synthesis of chiral benzodioxocines
Neogi, Arpita,Majhi, Tirtha P.,Achari, Basudeb,Chattopadhyay, Partha
, p. 330 - 336 (2008/09/18)
Palladium-catalyzed intramolecular aryl etherification using bulky binaphthylphosphane or bis(diphenylphosphanyl)ferrocene ligands is shown to be a convenient method for the synthesis of eight-membered oxygen heterocycles. Application of this methodology to a sugar derivative led to the synthesis of chiral benzodioxocine. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.
Radical cyclization of exo-methylene furanose derivatives: An expedient approach to the synthesis of chiral tricyclic nucleosides and benzannulated oxepine derivatives
Neogi, Arpita,Majhi, Tirtha Pada,Ghoshal, Nanda,Chattopadhyay, Partha
, p. 9368 - 9374 (2007/10/03)
Tributyltin radical mediated cyclization of the glucose derived exo-methylene furanose derivatives 5a-c led to the highly functionalized cis-fused bicyclic ethers 6a-c. The product could subsequently be transformed to the optically active tricyclic nucleoside analogue 8 or oxepine derivative 9.
Synthesis of chiral cis- and trans-furo[3,2-c][2]benzoxocines from D-glucose by regioselective 8-endo aryl radical cyclisation

A simple chiral synthesis of cis- and trans-furo[3,2-c][2]benzoxocines 8a-d and 9a-d through a regioselective 8-endo-trig aryl radical cyclisation of the respective 5,6-dideoxy-D-xylo-hex-5-enofuranosides 6a-d and 5,6-dideoxy-D-ribo-hex-5-enofuranosides 7
A simple construction of chiral fused benzoxocine ring ethers from D-glucose by regioselective 8-endo-aryl radical cyclisation
Chattopadhyay, Partha,Mukherjee, Monika,Ghosh, Soma
, p. 2139 - 2140 (2007/10/03)
A regioselective 8-endo-trig aryl radical cyclisation of the 5,6-deoxy-D-xylo-5-enofuranosides 3a and 3b with tri-n-butyltin hydride provides the chiral furo[3,2-c][2]benzoxocines 4a and 4b in good yields; the crystal structure of 4a is reported.
