Efficient Synthesis of 2-Methylene-3phosphorylalkanoates: Phosphorylation of Baylis–Hillman Bromides via an SN2-SN2′ Strategy
摘要:
A novel synthesis of 2-methylene-3-phosphorylalkanoates under mild conditions is described. Thus, Balyis-Hillman bromides react with secondary phosphine oxides or H-phosphonites in the presence of DABCO via an S(N)2-S(N)2' protocol to produce the target compounds in good yields.
