The synthesis of C(4)H and C(4)Me analogues of the JNK/p38 pathway activator anisomycin, based upon an aldol or Claisen construction of the C(3)–C(4) bond, has been demonstrated. The relative activation of the JNK/SAPK1 and p38/SAPK2 pathways in RAW macrophages by these analogues, and their synthetic precursors, has been assessed using immunoblot assays against phosphorylated c-Jun and MAPKAP-K2. These studies demonstrate that some of the synthetic C(4) analogues are also potent activators of these stress kinase pathways.

[reaction: see text] A new approach to the synthesis of the antibiotic anisomycin is reported that relies upon a key aldol disconnection. The glycolate aldol coupling proceeds in 75% yield and with >95% diastereoselectivity, which allows the 13-step synthesis to proceed in 35% overall yield.
