The invention provides a preparation method of 3-methylthio propylamine. The method is characterized in that under the effects of microwaves and ultrasonic waves, flavoring essence of 3-methylthio propyl alcohol capable of being easily obtained in China is used as a starting raw material; the reaction time is short; the total yield is relatively high. Under the effects of microwaves and ultrasonicwaves, firstly, 3-methylthio propyl alcohol and thionyl chloride react for 20 to 60 min under the back flow condition to prepare 3-methylthio-1-chloropropane, and the yield is greater than 95 percent; then, at 80 to 90 DEG C, the 3-methylthio-1-chloropropane and phthalimide potassium react for 0.5 to 2.5h to prepare N-3-methylthio propyl phthalimide, and the yield is greater than 94 percent; finally, the N-3-methylthio propyl phthalimide and hydrazine hydrate perform backflow reaction in absolute ethyl alcohol for 20 to 60min to prepare the 3-methylthio propylamine, and the yield is greater than 85 percent.

The fungi Helminthosporium species NRRL 4671 and Mortierella isabellina ATCC 42613 have been used for the biotransformation of a series of isothiocyanatoalkyl methyl sulfides and their synthetic precursors, ω-(methylthio)alkylphthalimides.H. species gave predominantly (S) sulfoxides in all cases; M. isabellina gave (R) isothiocyanatoalkyl methyl sulfoxides, but in the case of two ω-(methylthio)alkylphthalimides substantial conversion of sulfoxide to sulfone resulted in the isolation of the former with predominant (S) configuration.A correction is made of the previously reported configurations of two biotransformation products (Tetrahedron: Asymmetry, 1994, 5, 1129).

N-Substituted phthalimides (1,2) possessing a terminal thioether function in their side chain were irradiated with a high-pressure mercury lamp to give a variety of thiazacycloalkanol derivatives (3,7,9-13,16,17) with favored γ-, δ-, ε-, and ζ-hydrogen abstractions (Table 1), in moderate to fairly good yields.
