An expedited synthesis of the bioprotective agent JP4-039 is described from N-Boc-l-leucinal in 50% overall yield. The synthesis involves the use of an α,β-unsaturated diazoketone as the key intermediate, followed by a photochemical Wolff rearrangement in the presence of 4-amino-TEMPO (4-AT).
从N- Boc- 1-亮氨酸描述了生物保护剂JP4-039的快速合成,总产率为50%。合成过程涉及使用α,β-不饱和重氮酮作为关键中间体,然后在4-氨基-TEMPO(4-AT)存在下进行光化学Wolff重排。
