Myosmine is a chemical compound selected from the group consisting of tobacco alkaloids. It is composed of a pyridine and a Dihydropyrrolring.

Occurrence

Myosmine contained in tobacco plants. Furthermore, it could also be detected in the range of 0.2-2 ng / g in the nuts and maize.

Production

The synthesis of myosmine can be accomplished in various ways. One possibility is the reaction of an ester of the nicotinic acid with protected butyrolactam.

Biosynthetic myosmine can be obtained by dehydrogenation of nornicotine. Here, it is an intermediate in the degradation of nicotinic acid to nornicotine. That myosmine but could also be detected in plants which do not produce nicotine can still connect to other previously unknown biosynthetic pathways.

Properties

In myosmine is a yellowish solid with a melting range of 42-44 ° C, which slowly turns brown at room temperature.

Use

Myosmine can be used for the synthesis of nornicotine. For this purpose, it is reduced either with hydrogen on a palladium - charcoal catalyst or with sodium borohydride.
