Benzofurans or Isochromenes via the Ring-Opening Cyclization of Cyclopropene Derivatives with Organolithiums
摘要:
A new and efficient approach to benzocycles from cyclopropene derivatives is described. Deprotection by organolithiums and subsequent ring-opening cyclization of the related 2-cyclopropenyl phenyl or benzyl acetates generated benzofurans and isochromenes in one pot.
Synthesis of constrained arylpiperidines using intramolecular Heck or radical reactions
摘要:
Two intramolecular routes were experimented to reach the hexahydrobenzofuro[2,3-c]pyridine platform: a Heck and a radical reaction. The radical route was applicable to all substrates, whereas the Heck route was of limited use. The key adducts were obtained via a Mitsunobu condensation between halogenated phenols and an allylic alcohol, the 3-hydroxy-tetrahydropyridine. (C) 2001 Elsevier Science Ltd. All rights reserved.

A route to enable the preparation of 5-benzylidenyl-benzopyridyloxepine analogues was developed to continue our research in the field of nuclear hormone receptor modulators. The key steps are 1) a syn-stereoselective diboration of a tethered aryl alkyne; 2) an intramolecular Suzuki cross-coupling reaction, which forms in a stereo- and regiocontrolled fashion, the 5-exoalkylidenyl 7-membered ring imbedded

The present invention is directed to inhibitors of the interaction of menin with MLL and MLL fusion proteins, pharmaceutical compositions containing the same, and their use in the treatment of cancer and other diseases mediated by the menin-MLL interaction.
visible-light-driven, copper-catalyzed C(sp3)–O coupling of benzylic radicals with phenols is described for the first time. This operationally simple and robust process features mild conditions, broad scope, and high functional-group tolerance, enabling the construction of a diverse range of cyanoalkylated arylethers (33 examples). Key to this protocol is the dual role of copper salt that acts not
Abstract An efficient synthetic route to tricyclic isoxazoles via sequential copper-catalyzed 1,3-dipolar cycloaddition and palladium-catalyzed intramolecular arylation of isoxazoles is described. Based on these reactions, a convenient one-pot synthesis of the tricyclic isoxazoles from terminal alkyne and hydroximoyl chlorides by using a cascade process was also developed. An efficient synthetic route
