hydroxylamine stage and cyclized to provide the novel chiral bicyclic hydroxamic acids (2,4,6). Michael addition of allyl acrylate on nitroacetic acid derivatives followed by Pd(0) catalyzed intramolecular allyl transfer and subsequent reduction of the nitro group yielded a novel class of cyclic hydroxamic acids related to pyroglutamic acid.
通过锌-NH 4 Cl将硝基乙酰基(S)-脯氨酸酯(1,3,5)还原至羟胺阶段并环化以提供新型手性双环异羟肟酸(2,4,6)。丙烯酸烯丙酯在硝基乙酸衍生物上的迈克尔加成反应,然后Pd(0)催化分子内烯丙基转移,随后硝基还原,产生了与焦谷氨酸有关的新型环状异羟肟酸。
