Abstract
Asymmetrie Total Synthesis Asymmetrie total synthesis of S-(+)-argentilactone (2) was accomplished, using methyl-a-D-glucopyranoside (3) as carbohydrate template. Benzylidene acetal 5 was hydrolysed with tBuOOH/AlCl3 and further manipulated to produce the aldehyde 10. A Wittig reaction and subsequent oxidation of the anomeric position yielded the target argentilactone.
摘要:通过使用甲基-α-D-葡萄糖吡喃糖(3)作为碳水化合物模板,完成了S-(+)-argentilactone (2)的不对称全合成。苄亚甲基缩醛5经过t-BuOOH/AlCl3水解,并进一步处理得到醛10。Wittig反应和后续的缩醛位置氧化产生了目标argentilactone。
