On the stereoselectivity of alkenoxyl radical 6-exo-trig cyclizations
Schneiders, Nina,Gottwald, Thomas,Hartung, Jens
supporting information; experimental part, p. 797 - 800 (2009/07/05)
The investigated set of 6-exo-trig cyclizations occurs irreversibly and justifies the use of tetrahydropyran-derived transition structures for rationalizing 2,6-cis, 2,5-trans, and 2,4-cis stereoselectivity in ring-closure reactions of 1-, 2-, and 3-pheny
Bromoallenes as allyl dication equivalents in the presence or absence of palladium(0): Direct construction of bicyclic sulfamides containing five- to eight-membered rings by tandem cyclization of bromoallenes

A highly regioselective synthesis of bicyclic sulfamides is described. Based on our recent discovery that bromoallenes can act as allyl dication equivalents in the presence of a palladium catalyst and alcohol, we investigated tandem cyclization of bromoal
Stereoselective cyclization using palladium(II) catalyst via hemiacetal intermediates
Miyazawa, Masahiro,Hirose, Yukari,Narantsetseg, Magsarjav,Yokoyama, Hajime,Yamaguchi, Seiji,Hirai, Yoshiro
, p. 2883 - 2886 (2007/10/03)
A stereoselective palladium-catalyzed cyclization of 3-phenyl-7-hydroxy-5- heptenal was developed. The reaction was carried out to give 2,4,6-trisubstituted tetrahydropyran with highly controlled 4,6-cis stereochemistry.
