Synthesis of α,β-Unsaturated 4,5-Disubstituted γ-Lactones via Ring-Closing Metathesis Catalyzed by the First-Generation Grubbs′ Catalyst.
ChemInform, 2005Co-Authors: Mauro Bassetti, Andrea D'annibale, And Alessia Fanfoni, Franco MinissiAbstract:4-Methyl-5-alkyl-2(5H)-furanones have been prepared by ruthenium-catalyzed ring-closing metathesis of the suitable methallyl acrylates. Despite the Electron Deficiency of the conjugated double bond and of the gem-disubstitution of the allylic alkene moiety in the starting acrylates, the first-generation Grubbs' catalyst I proved to be an effective promoter for the ring closure, affording the expected butenolides in good to high yields
-
Synthesis of alpha,beta-unsaturated 4,5-disubstituted gamma-lactones via ring-closing metathesis catalyzed by the first-generation Grubbs' catalyst.
Organic letters, 2005Co-Authors: Mauro Bassetti, Andrea D'annibale, And Alessia Fanfoni, Franco MinissiAbstract:[reaction: see text] 4-Methyl-5-alkyl-2(5H)-furanones have been prepared by ruthenium-catalyzed ring-closing metathesis of the suitable methallyl acrylates.

correlation of the structure of chiral o o bisphenol ti iv complexes with ligand Electronic effects a relationship between lewis acidity and angle strain
Tetrahedron Letters, 1994Co-Authors: E J Corey, Michael A Letavic, Mark C Noe, Sepehr SarsharAbstract:Abstract The Electron Deficiency of Ti(IV) in complexes with chiral o,o′-bisphenols influences the CArOTi angle which, in turn determines the topology of the most stable (or easily formed) cyclic complex.

Boron served straight up
Nature Chemistry, 2014Co-Authors: Christian Reus, Matthias WagnerAbstract:Borinium ions are difficult to isolate due to the extreme Electron Deficiency of the boron atom. Now, a unique two-coordinate linear dimesitylborinium cation has been synthesized that impresses with extraordinary Lewis acidity and oxophilicity.
