A Practical Synthesis of m-Prostaglandin E Synthase-1 Inhibitor MK-7285
摘要:
A practical, kilogram-scale chromatography-free synthesis of mPGE synthase I inhibitor MK-7285 is described. The route features a convergent assembly of the core phenanthrene unit via amide-directed ortho-metalation and proximity-induced anionic cyclization, followed by imidazole synthesis and late-stage cyanation.
The present invention relates to a compound represented by the following formula (1):
wherein W, X, Y, R1, R2, R33, R34, m and n are as defined in the claims, or a pharmacologically acceptable salt thereof.
