Enantioselective Synthesis of Nicotine via an Iodine-Mediated Hofmann-L?ffler Reaction

An iodine-mediated Hofmann-L?ffler reaction has been developed that enables the first enantioselective synthesis of nicotine based on this synthetic methodology. The effect of the free pyridine core on the involved electrophilic iodine reagents was explored in detail. The final synthesis proceeds under moderate reaction conditions that tolerate the free pyridine core. The same synthetic sequence is also applicable to a number of derivatives with higher substituted pyridine cores, including bipyridine derivatives.

The biosynthesis of [5'-14C]cotinine and other radiolabeled nicotine metabolites

The present study describes the biosynthesis and isolation of the major radiolabeled nicotine metabolites formed using phenobarbitone (PB)-induced rabbit hepatic homogenates (10,000 g fraction). The optimal incubation and extraction methods for cotinine formation from non-labeled nicotine were established. The biosynthesis and isolation of [5'-14C]cotinine and other radiolabeled metabolites such as [2'-14C]nornicotine and [4-14C]-(3-pyridyl)-4-oxobutyric acid, from commercially available [2'-14C]nicotine, were carried out using the developed methods. Cotinine was isolated using preparative silica gel TLC, whereas the other metabolites were obtained using a cation-exchange HPLC method. This study showed that in addition to the two major metabolites (i.e. cotinine and nornicotine), 4-(3-pyridyl)-4-oxo-butyric acid, 3-hydroxycotinine, norcotinine, nicotine-1'-N-oxide and cotinine-1-N-oxide were also formed when PB-induced rabbit hepatic homogenates were used. Two further metabolites of unknown structure were detected. However, the isolation and further purification were only carried out on cotinine, nornicotine and 4-(3-pyridyl)-4-oxo-butyric acid.

A short and efficient synthesis of unnatural (R)-nicotine is described, in which the key step is an intramolecular hydroboration-cycloalkylation of an azido-olefin intermediate. The synthesis is achieved in only four steps, with an overall yield of 51% (or in six steps with an overall yield of 65%). (C) 2000 Elsevier Science Ltd.

ABILITY OF A NICOTIANA PLUMBAGINIFOLIA CELL SUSPENSION TO DEMETHYLATE NICOTINE INTO NORNICOTINE

A cell suspension of Nicotiana plumbaginifolia which does not accumulate tobacco alkaloids was found to keep the ability to demethylate nicotine into nornicotine.The highest bioconversion yield was 53.2 percent.The influence of some environmental factors upon the reaction has been studied.In particular, it appears that light enhances the catalytic activity of the cells which leads to the hypothesis that this metabolic step of tobacco alkaloids is bound to photodependent systems.

Orthogonal Catalysis for an Enantioselective Domino Inverse-Electron Demand Diels?Alder/Substitution Reaction

An enantioselective domino process for the synthesis of substituted 1,2-dihydronaphthalenes has been developed by the combination of chiral amines and a bidentate Lewis acid in an orthogonal catalysis. This new method is based on an inverse electron-demand Diels?Alder and a subsequent group exchange reaction. An enamine is generated in situ from an aldehyde and a chiral secondary amine catalyst that reacts with phthalazine, activated by the coordination to a bidentate Lewis acid catalyst. The absolute configuration of the product is controlled by chiral information provided by the amine. The formed ortho-quinodimethane intermediate is then transformed via a group exchange reaction with thiols. The new method shows a broad scope and tolerates a wide range of functional groups with enantiomeric ratios up to 91 : 9. All-in-all, this enantioselective synthesis tool provides an easy access to complex 1,2-dihydronaphthalenes starting from readily available phthalazine, aldehydes and thiols in a combinatorial way.
