Telescoped Synthesis of Stereodefined Pyrrolidines

Organic Letters, 2013
Telescoped and one-pot olefination/asymmetric functionalization approaches to disubstituted pyrrolidines (dr up to 99:1, up to 99% ee) have been developed using commercially available tetramisole (0.1 to 5 mol %). Using OTMS-quinidine as the Lewis base gives preferential access to an anti-configured pyrrolidine in high enantioselectivity.

Pyrrolidine dithiocarbamate reduced experimental periodontitis

European Journal of Pharmacology, 2006
Nuclear factor-kappaB (NF-kappaB) is a transcription factor which plays a pivotal role in the induction of genes involved in physiological processes as well as in the response to injury and inflammation. Dithiocarbamates are antioxidants which are potent inhibitors of NF-kappaB.

Synthesis of pyrrolidine-2–14C

Journal of Pharmaceutical Sciences, 1967
The preparation of pyrrolidine-2– 14 C picrate in satisfactory yields from potassium cyanide- 14 C and from barium carbonate- 14 C is reported. Reaction of pyrrolidine picrate with lithium hydroxide followed by distillation separated the free base.

[60]Fullerene−Pyrrolidine-N-oxides

The Journal of Organic Chemistry, 2006
Eight members of a new family of fullerene derivatives, [60]fulleropyrrolidine-N-oxides, have been synthesized and characterized. Facile oxidation, by a peracid, of the parent [60]fulleropyrrolidine gave clean conversions into the product molecules, in which the tertiary amine is transformed into a quaternary amine bearing an oxygen atom.

Syntheses de Pyrrolidines Deuteriees

Journal of Labelled Compounds, 1974
AbstractCinq pyrrolidines di ou tétradeutériées ont été préparées soit par réduction de la cétone correspondante (dideutério‐2,2 pyrrolidine), soit à partir du dérivé N nitrosé après échange en milieu basique (tétradeutério‐2,2,5,5 pyrrolidine) soit enfin par cyclisation d'une chaǐne aliphatique marquée en position souhaitée (dideutério‐3,3 ...

Organophosphorus derivatives of pyrrolidine

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1974
Some 2-oxo-2-pyrrolidino-1,3,2-dioxaphospholanes and the corresponding phosphorinanes, and also some 2-thio-2-pyrrolidino-1,3,2-dioxaphospholanes (phosphorinanes), were obtained for the first time. These compounds have an antispasmodic effect and the ability to depress the central nervous system.
