发明名称 Novel method of producing 1,2,3-trithiane compounds.
摘要 <p>This invention relate to a process for producing a 1,2,3-trithiane compound of the general formula: &lt;Chemistry id="chema01" num="0001"&gt;&lt;Image id="ia01" he="19" wi="83" file="IMGA0001.TIF" imgContent="chem" imgFormat="TIFF" inline="no" /&gt;&lt;/Chemistry&gt;wherein each of R, and R&lt;Sub&gt;2&lt;/Sub&gt; is independently a lower alkyl group, or alternatively, R, and R&lt;Sub&gt;2&lt;/Sub&gt; together with the adjacent nitrogen atom form a 5-or 6-membered heterocyclic group which may further contain an oxygen, sulfur or nitrogen atom, or a salt thereof, which comprises reacting a compound of the general formula: &lt;Chemistry id="chema02" num="0002"&gt;&lt;Image id="ia02" he="26" wi="84" file="IMGA0002.TIF" imgContent="chem" imgFormat="TIFF" inline="no" /&gt;&lt;/Chemistry&gt;wherein R&lt;Sub&gt;1&lt;/Sub&gt; and R&lt;Sub&gt;2&lt;/Sub&gt; are as defined above, or a salt thereof with a compound of the general formula: &lt;Chemistry id="chema03" num="0003"&gt;&lt;Image id="ia03" he="5" wi="74" file="IMGA0003.TIF" imgContent="chem" imgFormat="TIFF" inline="no" /&gt;&lt;/Chemistry&gt;wherein Me is hydrogen, an alkali metal atom or an ammonium radical under an acid condition.</p><p>The compound (I) or a salt thereof is produced in high purity and high yield according to the process of this invention.</p>
