A short (10 step) and efficient (15% overall yield) synthesis of the natural product (−)-(3R)-inthomycin C is reported. The key steps comprise three C–C bond-forming reactions: (i) a vinylogous Mukaiyama aldol, (ii) an olefin cross-metathesis reaction, and (iii) an asymmetric Mukaiyama–Kiyooka aldol. This route is notable for its brevity and has the advantage of lacking stoichiometric tin-promoted
据报道,天然产物(-)-(3 R)-霉素C的合成过程很短(10个步骤),有效合成(总产率为15%)。关键步骤包括三个C–C键形成反应:(i)乙烯基Mukaiyama-Aldol,(ii)烯烃交叉复分解反应,以及(iii)不对称Mukaiyama-Kiyooka aldol。该路线以其简洁而著称,其优点是缺乏先前方法中存在的化学计量的锡促进的交叉偶联反应。还首次描述了对人类癌细胞系中(-)-(3 R)-霉素C和结构类似物的生物学活性的初步研究。
