Kim, Jae Gon,Son, Young Hoon,Seo, Jin Won,Kang, Eun Joo
supporting information, p. 1781 - 1789 (2015/05/27)
A range of arylmethyl-substituted pyrrolidines and tetrahydrofurans were produced by FeCl2-catalyzed tandem cyclization and cross-coupling reactions of alkyl iodides and aryl Grignard reagents. The substituents on alkenes had a profound effect

Aliphatic acyclic and cyclic ethers are prepared on treatment of their corresponding carboxylic esters and lactones with triethylsilane in the presence of titanium tetrachloride and trimethylsilyl trifluoromethanesulfonate.
Tungsten(0) alkylidene complexes stabilized as pyridinium ylides: New aspects of their synthesis and reactivity
Rudler, Henri,Durand-Réville, Thomas
, p. 571 - 587 (2007/10/03)
The interaction of dihydropyridines with alkoxycarbene complexes of tungsten has been shown to lead to pyridinium ylid complexes: this transformation has now been applied to the synthesis of a hydroxyl-containing ylid complex by ring-opening of the pentacarbonyl (2-oxacyclopentylidene) tungsten(0) complex and to the synthesis of a series of chiral ylid complexes both from chiral and non-chiral carbene complexes by the use of dihydropyridines and dihydronicotines, respectively. The transfer of the alkylidene moiety of these complexes to nucleophilic olefins will be outlined and discussed. Especially relevant is the interaction of these pyridinium ylid complexes with unsaturated substrates such as dihydropyridines, enamines, and β-alkoxy bis(trimethyl-silyl) ketene acetals. This latter reaction leads to conjugated carboxylic acids, and has been be applied to a new synthesis of a honey bee pheromone, the queen substance.
Aryloxymethyl Radical Cyclizations Mimicking Biological C-C Bond Formation to Methoxy Groups
Ahmad-Junan, S. Asiah,Walkington, Andrew J.,Whiting, Donald A.
, p. 2313 - 2320 (2007/10/02)
Attention is drawn to a small group of diverse natural products whose biosynthesis is unusual in involving formation of O-heterocyclic rings by C-C bond formation to aromatic methoxy groups, in net oxidative and non-oxidative processes.It is shown that ar
CYCLODESHYDRATION DE DIOLS EN PRESENCE D'HMPT1
Diab, J.,Abou-Assali, M.,Gervais, C.,Anker, D.
, p. 1501 - 1502 (2007/10/02)
1,4 and 1,5-diols heated with 0.3 equivalent of HMPA undergo cyclodehydration leading to tetrahydrofurans and tetrahydropyrans.
Stereochemical Assignment of the 6-Phenyl-2-oxabicyclohexanes
Schaub, Lowry P.,Woodyard, James D.
, p. 1237 - 1238 (2007/10/02)
Preparation and stereochemical assignments of the 6-phenyl-2-oxabicyclohexanes are reported.The stereochemical assignments are based on chemical as well as nmr data.
A RADICAL DEOXYGENATION OF PRIMARY ALCOHOLS BY USE OF TRI-n-BUTYLTIN HYDRIDE - SODIUM IODIDE, AND ITS APPLICATION TO A RADICAL CYCLIZATION
Ueno, Yoshio,Tanaka, Chie,Okawara, Makoto
, p. 795 - 796 (2007/10/02)
Primary alcohols are deoxygenated to hydrocarbons via tosylates with tri-n-butyltin hydride-sodium iodide under mild radical conditions; the method is useful for the preparation of cyclic compounds from acyclic ones possessing primary hydroxyl and olefinic groups by reductive cyclization.
