General Description

2-Methyl-piperidine hydrochloride is a chemical compound that consists of a piperidine ring with a methyl group attached to the second carbon. It is commonly used as a building block in the synthesis of pharmaceuticals and agrochemicals. 2-METHYL-PIPERIDINE HYDROCHLORIDE is also used as a stabilizer for some polymers and as a reagent in organic chemistry reactions. 2-Methyl-piperidine hydrochloride is a white crystalline powder that is soluble in water and alcohol. It is important to handle this chemical with care, as it can cause skin and eye irritation.

Nonracemic betti base as a new chiral auxiliary: Application to total syntheses of enantiopure (2S,6R)-dihydropinidine and (2S,6R)-isosolenopsins

(Chemical Equation Presented) Total syntheses of enantiopure alkaloidal natural products (2S,6R)-dihydropinidine (as hydrochloride) and (2S,6R)-isosolenopsins (as hydrochlorides) were achieved in four steps and in 80-82% total yields by using a synthetic strategy of the formation-cleavage of 1,3-oxazinane.

A simple stereoselective synthesis of enantiopure 2-substituted pyrrolidines and piperidines from chiral (R)-phenylglycinol-derived bicyclic 1,3-oxazolidines

Chiral, nonracemic 2-substituted pyrrolidines and piperidines were prepared in high ee and moderate to good chemical yields in three steps from (R)-phenylglycinol and γ- or δ-chloroketones. The key step of the synthesis was the stereo- selective reductive ring-opening of chiral bicyclic 1,3- oxazolidines prepared by condensation of (R)-phenylglycinol and the corresponding ketones.

Synthesis of azetidine, pyrrolidines and piperidine by intramolecular cyclization of ω-Azidoboranes.

This paper describes the development of efficient routes to azetidine, pyrrolidines and piperidines by creation of a carbon-nitrogen bond.Two complementary syntheses of these heterocycles were studied : the cyclization of ω-azidoboronic esters by treatment with boron trichloride, and the one pot hydroboration of an ω-azidoalkene and intramolecular reductive alkylation.The scope and limitations of these two promising approaches are reported.Keywords: azides / boronic esters / boranes / intermolecular cyclization / azetidine / pyrrolidine / piperidine / pyrrolizidine
