The invention relates to a new process for preparing carbamate derivatives having the structure of formula (I) by reacting, in a first step, a compound of formula (II) with a compound of formula (III) and reacting the product of this first step with an acylating agent of formula (V).
The first aryliodide catalyzed intramolecular C–H amination of phenylurea has been disclosed for high-efficiency synthesis of benzimidazolone derivatives in excellent yields (up to 97%) by an operationally simple one-step organocatalytic oxidative process. Fluorinated protic alcohols can efficiently accelerate the conversion of this transformation. The straightforward method has good functional group

annulation of aryl iodides and aryl carbamic chlorides for the efficientsynthesis of phenanthridinone derivatives was developed. Simple aryl iodides and carbamic chlorides readily made from various anilines, a broad substrate scope with hetero/polycycles, as well as high-value products, make this direct dehydrogenative annulation approach very practical and attractive.
