2, 4, 6-Trithiaheptane (1 a) has been prepared by lithium tetrahydridoaluminate reduction of the methiodide of 1, 3, 5-trithiane (2). Treatment of 1 a with strong bases permitted formation of 3-alkylated derivatives (3) which could in turn be converted into diastereomeric mixtures of 3, 5-dialkyl derivatives (4). A two-step alkylation of 1 a with 1-bromo-3-chloropropane led to the formation of 2, 6-bis (methylthio) thiane (5). Proton and 13C nmr spectral studies on ...
