2-Methylnicotine is a major product in the reaction of nicotine with methyllithium and methyl radical, in addition to the previously reported 4- and 6-methylnicotines. The reaction of nicotineN-oxide with methylmagnesium bromide furnishes both 2- and 6-methylnicotine.

2-Alkyl-nicotinoids represented by formula (I)
wherein R1 is hydrogen, lower alkyl, phenyl alkyl or aralkyl, R2 is lower alkyl or phenyl alkyl, and R3 is represented by the formula:
wherein R4 is hydrogen or lower alkyl, Rs is lower alkyl, and n is one or two, which are prepared according to the schema:
wherein X =chlorine,bromine,
iodine or
fluorine I
The compounds of formula (i) are useful as insecticides.
The use in the treatment of neurodegenerative disease is described of a substituted nicotine compound having the formula (1):
where R represents H or alkyl, R¹ represents alkyl, X represents halo or alkyl, n represents an integer from 0-4 and m represents an integar from 0-3, provided that n plus m equals at least 1.
Exemplary nicotine compounds are 5-fluoronicotine, 5-bromonicotine, 4¹-methylnicotine and 5-methylnicotine.
