The compounds are obtained by using carvone as an initial raw material through chlorination reaction, condensation reaction, sodium borohydride reduction and Huang Min-lon reduction reaction.
Methods 1-Methyl-1,2,3,4-tetrahydroisoquinoline was synthesized from phenethylamine through three steps:acetylation with acetyl chloride, cyclization with PPA and reduction with potassium borohydride.
