Process to prepare chloroketoamines using carbamates |
摘要 |
The present invention relates to a process for preparing 5-methylene cyclic carbamates either by cyclization of an alkynyl amine with carbon dioxide in the presence of a copper catalyst or by forming an isocyanate from a substituted acetoacetamide followed by hydrolysis. The 5-methylene cyclic carbamates by either method are converted to 5-(chloromethylene) cyclic carbamates, using trichloroisocyanuric acid, followed by hydrolysis to a chloroketoamine. The chloroketoamine from the process of this invention additionally can be reacted with an organic acid chloride to form an amide compound which is useful as a fungicide. |
