scheme or table, (2010/04/22)
A miniflow system for oxidative cyclization of alkenols with Oxone was developed. Thus, the oxidative cyclization of (Z)- and (E)- alkenols in i-PrOH with an aqueous solution of Oxone proceeded smoothly and safely in a PTFE tube without any exogenous catalytic species, and was subsequently quenched in a flow-reaction manner to afford the corresponding furanyl and pyranyl carbinols quantitatively within 5 or 10 min of residence time.

Equation Presented A tightly convoluted polymeric phosphotungstate catalyst was prepared via ionic assembly of H3PW12O40 and poly(alkylpyridinium). An oxidative cyclization of various alkenols and alkenoic acids was efficiently promoted by the polymeric catalyst in aq H 2O2 in the absence of organic solvents to afford the corresponding cyclic ethers and lactones in high yield. The catalyst was reused four times without loss of catalytic activity.

Lithium tri-n-butyl borohydride showed high selectivity in the reduction of α- and β-oxygenated ketones, giving a preponderance of the chelation controlled products.
DIASTEREOSELECTIVITE DANS LA REACTION DES ORGANOMAGNESIENS SUR LE TETRAHYDROFURFURAL ET SON GEM-DIACETATE EN PRESENCE DE HMPT. ACCES AUX DIOLS-1,2 ERYTHRO.

Grignard Reagents - HMPT complexes have been found to be highly stereoselective reagents for the addition to tetrahydrofurfural and for the substitution of an acetoxy group in tetrahydrofurfural gem-diacetate.In both cases, a high erythro/threo ratio was obtained.
