1,3,5,-Triaza-7-phosphaadamantane (PTA) is first reported to be a convenient and efficient nucleophilic trialkylphosphine organocatalyst for the Baylis–Hillman reaction. Thus, under the mediation of 15–20 mol % of PTA and practical conditions, both aromatic and aliphatic aldehydes react with the activated alkenes like acrylates and methyl vinyl ketone to afford the corresponding adducts in fair to
1,3,5,-Triaza-7-phosphaadamantane(PTA)首次被报道是一种用于Baylis-Hillman反应的便捷有效的亲核三烷基膦有机催化剂。因此,在15-20 mol%的PTA和实际条件下,芳族和脂族醛均与活化的烯烃(如丙烯酸酯和甲基乙烯基酮)反应,以相当高的收率获得相应的加合物。
