Ring Opening Alkylation of Tetrahydrofuran with Some Heterosubstituted Organolithium Reagents by the Aid of Boron Trifluoride Etherate
Imai, Toshiro,Muramoto, Tomoki,Tsuji, Takashi
, p. 355 - 356 (1995)
Organolithium reagents stabilized by halogeno, thio, silyl, vinyl and/or phenyl substituent(s) can cleave THF effectively under the influence of boron trifluoride etherate at lower temperatures.The softness of these carbanionic reagents seems to be import
Titanocene(II)-promoted olefination of ω,ω-bis(phenylthio)alkyl alkanoates. A new method for the preparation of ω-hydroxy ketones
Rahim, Md. Abdur,Fujiwara, Tooru,Takeda, Takeshi
, p. 763 - 770 (2007/10/03)
Intramolecular olefination of esters having a thioacetal moiety was studied. The treatment of ω,ω-bis(phenylthio)alkyl alkanoates with Cp2Ti[P(OEt)3]2 and the following hydrolysis gave ω-hydroxy ketones in good yields. (C) 2000 Elsevier Science Ltd.
Catalyst-dependent selective synthesis of O/S- and S/S-acetals from enol ethers
Braga,Silveira,Dornelles,Zeni,Galarza,Wessjohann
, p. 3155 - 3162 (2007/10/02)
Enol ethers are reacted with mercaptanes to give the corresponding O/S- or S/S-acetals in medium to high yield. Either product can be formed selectively depending on the acid catalyst and the reaction time applied.
Carbenoid Anion Behavior of Dilithio Derivatives of Thioacetal Alcohols. Stereochemistry and Mechanism of Ring Closures by Oxyanion-Facilitated CH Bond Insertion
Ritter, Robert H.,Cohen, Theodore
, p. 3718 - 3725 (2007/10/02)
Like other lithio derivatives of thioacetals bearing a second anionic site, dilithio derivatives of 3,3-, 5,5-, and 6,6-bis(phenylthio) alcohols decompose at or below ambient temperature to yield products ascribable to carbenoid intermediates.The 5,5-deri
MONOTHIOACETALIZATION OF ACETALS USING DIETHYLALUMINIUM THIOPHENOXIDE
Masaki, Yukio,Serizawa, Yuzuru,Kaji, Kenji
, p. 1933 - 1936 (2007/10/02)
Reactions of diethylaluminium thiophenoxide (Et2AlSPh) with acetals of several types, in which acyclic, cyclic, and bicyclic ones are involved, were examined in comparison with the known reaction using thiophenol in the presence of Lewis acid and found to provide a new and efficient method for preparation of monothioacetals.
