The total synthesis of 15-membered peptide alkaloids abyssenine B and mucronine E was accomplished via olefination of phenylalanine-embodied aldehydes followed by CuI/N,N-dimethylglycine-catalyzed coupling of vinyl iodides with amides and FDPP-mediated macrocyclization in the key steps. From the total synthesis the stereochemistry of these two natural products was tentatively assigned to be S,S,S.
15员肽生物碱Asssenine B和mucronine E的总合成是通过苯丙氨酸键合的醛的烯化,然后CuI / N,N-二甲基甘氨酸催化的乙烯基碘与酰胺的偶联以及FDPP介导的大环化来完成的。从全合成中,这两种天然产物的立体化学暂定为S,S,S。
