A Synthesis of Cyanolide A by Intramolecular Oxa-Michael Addition
摘要:
A synthesis of cyanolide A, a diolide natural product, has been achieved using a diastereoselective Barbier reaction, early-stage glycosylation, and intramolecular oxa-Michael addition to form the THP ring.

tetradeuterated synthon to the appropriated alkynol and a double chemoenzymatic strategy to resolve the alcohol functionality allowed one to obtain the enantiomerically enriched probes used in the mechanistic studies. Massspectrometric analyses of extracts from tissues cultured with each probe revealed that removal of the C13 and C14 hydrogens in 11-hexadecynoate and (Z)-11-hexadecenoate are pro-(R)-

Recognizing the value of including complex pyridines in small-molecule screening collections, we developed a previously unexplored [2 + 2 + 2]-cycloaddition of silyl-tethered diynes with nitriles. The tether provides high regioselectivity, while the solvent THF allows Catalytic CpCo(CO)(2) to be used without exogenous irradiation. One of the resulting bicyclic and monocyclic (desilylated) pyridines was identified as an inhibitor of neuregulin-induced neurite outgrowth (EC(50) = 0.30 mu M) in a screen that probes a pathway likely to be involved in breast cancers and schizophrenia.
