摘要： A method of making chlorins comprises the steps of reacting (e.g. condensing) a dipyrrin western half intermediate with an eastern half intermediate to form a tetrahydrobilene, and then cyclizing the tetrahydrobilene to form a chlorin. Intermediates including tetrahydrobilenes useful in such reactions are also described.

摘要翻译： 制备二氢卟酚的方法包括使双吡啶西半中间体与东半中间体反应（例如缩合）以形成四氢苯乙烯的步骤，然后环化四氢苯并形成二氢卟酚。还描述了包括在这种反应中有用的四氢噻吩的中间体。
