The cycloaddition reaction of aromatic thioketones (aryl naphthyl thioketones and 2-benzofuryl phenyl thioketone) with 2-chloroacrylonitrile followed by elimination of hydrogen chloride gave some 2H-thiin derivatives. The products reacted with MCPBA and an alcohol to afford ring-contracted product and alkoxylated derivatives.
芳香硫酮(芳基萘硫酮和2-苯并呋喃苯基硫酮)与2-氯丙烯腈的环加成反应后,通过氯化氢的消除得到一些2H-噻烷衍生物。产物与MCPBA和醇反应,生成环收缩产物和醇醚化衍生物。
