Novel N-sulfonyl β-amino acids were efficiently prepared in a seven-step synthesis starting from Boc protected methanesulfonamide and terminal epoxides. A zinc-mediated allylation of cyclic N-sulfonyl imines readily derived from these building blocks served as a key operation of this sequence.
从Boc保护的甲磺酰胺和末端环氧化物开始,以七步合成法有效地制备了新型N-磺酰基β-氨基酸。容易衍生自这些结构单元的环状N-磺酰基亚胺的锌介导的烯丙基化作用是该序列的关键操作。
