A new approach to 2,3-disubstituted cyclopentenones has been developed. This approach consists of a two-step protocol involving the cyclization of a Z-vinyl bromide under Barbier type conditions to form a cyclopentenol, which is then oxidatively rearranged to generate the cyclopentenone. The Z-vinyl bromide is in turn derived from a ruthenium catalyzed three-component coupling of an alkyne, an enone
已经开发出一种新的2,3-二取代的环戊烯酮的方法。该方法由两步方案组成,涉及在Barbier型条件下将Z-乙烯基溴化物环化以形成环戊烯醇,然后将其氧化重排以生成环戊烯酮。Z-乙烯基溴化物又衍生自炔烃,烯酮和HBr等价物的钌催化的三组分偶联。已经产生了各种2,3-二取代的环戊烯酮,包括茉莉酮和二氢茉莉酮的短合成。该策略的进一步适用性在四氢二烯酮B,罗沙前列醇和选择性COX-2抑制剂的总合成中显示。
