Paragraph 0060-0061, (2021/11/03)
The invention discloses a method for synthesizing chiral nicotine from butyrolactone. The fumarates and γ - butyrolactone are condensed under the action of a basic catalyst to yield 4 - chloro -1 - (3 - pyridine) -1 -butanone by reaction with hydrochloric acid and reacted with a chlorination reagent to produce (- B -) S (-4 -1 -dichlorobutyl) pyridine which is reacted with an amine reagent under basic conditions to give (-3 -) -1 -methyl nicotine and (S)-3 - nicotinic acetylbutanolamines obtained by the reaction with the aminating reagent under an alkaline condition to produce a chiral hydroxy S S group - (1) S- methylnicotine or a (4 -) S nicotinic acid. The application can determine whether a methylation reaction is needed according to the type of amination reagent. The yield of (S)- nicotine was high.
