Nicotine laboratory synthesis

The alkylation can be intramolecular, as in the following final step in a laboratory synthesis of nicotine ...

The breakdown pathways for NAD and NADP were discussed in the section on electron transport. Studies in Pardee s laboratory have shed some new light on the control of NAD synthesis in E. coli (see Fig. 4-10). Pardee was able to demonstrate that in the sequence of reactions, the NAD mononucleotide pyrophosphorylase reaction is the rate-limiting step. The levels of pyrophosphorylase are low in the wild type of E. coli, but they are even lower in mutants requiring nicotinic acid for growth when the bacteria...
