The rhodium-catalyzed C-H activation and annulation with ynol ethers to directly provide 4-oxy substituted isoquinolinones is reported. The polarized nature of ynol ethers provides an electronic bias for controlling the regioselectivity of the migratory insertion process. While the highly reactive nature of ynol ethers presents a challenge, mild conditions were found to provide product in moderate to good yield. Utility was demonstrated by application in the synthesis of a prolyl-4-hydroxylase inhibitor framework.
Asymmetric addition of aryloxy ethynyl lithium derivatives to N-sulfinyl imines
Verrier, Charlie,Carret, Sebastien,Poisson, Jean-Francois
, p. 455 - 460 (2013/07/26)
Aryloxy ethynyl lithium species can be generated in diethyl ether and efficiently added to aliphatic and aromatic N-sulfinyl imines in THF, affording aryloxypropargyl sulfinamides in good yield, and in most cases high diastereoselectivity. The diastereose
