Mechanistic insight into the acid-catalyzed isomerization of biomass-derived polysubstituted pyrrolidines: an experimental and DFT study
(Royal Society of Chemistry, 2017-01)
The 1,3-dipolar cycloaddition reactions of azomethine ylides is one of the preferred methods for the synthesis of polysubstituted pyrrolidines. The use of chiral dipolarophiles derived from carbohydrates yields enantiomerically ...

Stereospecific Synthesis of Pyrrolidines with Varied Configurations via 1,3-Dipolar Cycloadditions to Sugar-Derived Enones
(American Chemical Society, 2014-05)
Enantiomerically pure pyrrolidines have been obtained by 1,3-dipolar cycloaddition of stabilized azomethine ylides and sugar enones (dihydropyranones) derived from pentoses. Thus, the S-enone (menthyl 3,4-dideoxy-(1S)-pe ...
Comment on "structural and vibrational studies on 1-(5-Methyl- [1,3,4] thiadiazol-2-yl)-pyrolidin-2-ol" [Spectrochimica Acta Part A, 152 (2016) 252-261]. the importance of intramolecular OH ⋯ N hydrogen bonding in the conformational properties of thiadiazol-pyrrolidin-2-ol bearing species
(Pergamon-Elsevier Science Ltd, 2016-07)
The title paper [1] reports a study on the spectroscopic and physicochemical properties of 1-(5-methyl- [1,3,4]thiadiazol-2-yl)-pyrrolidin-2-ol (MTPN) based on experimental and theoretical data. The latter ones are based ...
Synthesis of Highly Substituted and Enantiomerically Pure 2,3,4-Tris(hydroxyalkyl)pyrrolidines Using a 1,3-Dipolar Cycloaddition Reaction as Key Step
(Wiley-Blackwell, 2017-06)
The major endo cycloadducts with a basic structure of methyl 1-aryl-3-(benzyl or methyl)-6-menthyloxy-7-oxooctahydropyrano[4,3-c]pyrrole-3-carboxylate were subjected to simple chemical transformations (mostly reduction and ...
Cladistic relationships in the genus Schizanthus (Solanaceae)
(2002)
The cladistic relationships between Schizanthus species, based primarily on morphology, and chemical characters when available are presented. In this investigation we did not find supporting evidence for the theories ...
