The novel reaction of [hydroxyl (((+)‐10‐camphorsulfonyl)oxy)iodo]benzene (1) with alkenoic acids was reported. When 1 reacted with various 4‐pentenoic acids in CH3CN, camphorsulfonylactons were obtained in excellent yields in short times, some had two diastereoisomers, whereas 1 reacted with 5‐hexenoic acid, giving middle yield of camphorsulfonylacton; however, 3‐butenoic and trans‐3‐hexenoic acids
报道了[羟基(((+)-10-樟脑磺酰基)氧基)碘]苯(1)与烯酸的新型反应。当1与CH 3 CN中的各种4-戊烯酸反应时,在短时间内以优异的产率获得了樟脑磺酰内酯,其中一些具有两个非对映异构体,而1与5-己酸反应,得到了中等的樟脑磺酰内酯。然而,3-丁烯酸和反式-3-己酸在CH 2 Cl 2中与1缓慢反应,仅提供不饱和内酯。J.杂环化学。(2010)。
