A general synthesis approach to pyrroloquinolizidines (3,4,5,5a,6,7,8- heptahydropyrrolo[2,1,5-de]-quinolizines) via a muenchnone 1,3-dipolar cycloaddition is reported. The approach was applied to the synthesis of an unnatural pyrroloquinolizidine homologue of myrmicarin 215B.
Diels-Alder reactions of 6-substituted 1-(p-nitrobenzoyl)-5,6-dihydro-2-pyridinones

, p. 100 - 104 (2007/10/03)
The first examples of Diels-Alder cycloaddition reactions of 6-substituted 1-(p-nitrobenzoyl)-5,6-dihydro-2-pyridinones are described. This reaction benefits from the fact that the diene adopts an endo orientation trans to the axial substituent at C-6 due to A1,3 allylic type strain with the N-PNB protecting group.
Convenient preparations of racemic and enantiopure methyl 6-oxopipecolate
Davies, Catherine E.,Heightman, Thomas D.,Hermitage, Stephen A.,Moloney, Mark G.
, p. 687 - 696 (2007/10/03)
Short, convenient syntheses of racemic and enantiopure methyl 6-oxopipecolate are described, starting from either pipecolic acid or (S)-lysine respectively. The sequence for the latter compound relies upon improved methodology for the oxidation of C-6 of
