Solid-phase synthesis of functionalized tropane derivatives via 1,3-dipolar cycloaddition
Caix-Haumesser, Sandrine,Hanna, Issam,Lallemand, Jean-Yves,Peyronel, Jean-Fran?ois
, p. 3721 - 3723 (2001)
1,3-Dipolar cycloaddition of 3-oxidopyridinium betaine to activated olefins on solid-phase leads to resin-bound 8-azabicyclo[3.2.1]octenones which undergo further transformations such as 1,4-addition of nucleophiles. Cleavage of benzyl linker is achieved
Structure of the Calystegines: New alkaloids of the nortropane family
Ducrot,Lallemand
, p. 3879 - 3882 (2007/10/02)
Three new alkaloids have been isolated from Calystegia sepium; their structures have been established from their 1H and 13C N.M.R. spectra, and confirmed by the synthesis of model compounds.
