the total synthesis of Paecilomycins E (1) and F (2), Cochliomycin C (4) and 6-epi-Cochliomycin C (3) is described. The synthesis involves novel route to the synthesis of Paecilomycin E and F and further conversion to Cochliomycin C and 6-epi-Cochliomycin C. Olefin metathesis and base promoted macro lactonization being the key reactions followed by chlorination to achieve target Cochliomycin C and
摘要描述了一种高效、简洁的方法来全合成拟青霉素 E (1) 和 F (2)、Cochliomycin C (4) 和 6-epi-Cochliomycin C (3)。该合成涉及合成拟青霉素 E 和 F 并进一步转化为 Cochliomycin C 和 6-epi-Cochliomycin C 的新途径。烯烃复分解和碱促进大环内酯化是关键反应,然后氯化以达到目标 Cochliomycin C 和 6-epi -Cochliomycin C. 图形摘要
