, p. 2357 - 2358 (2007/10/02)
Trimethylsilyl trifluoromethanesulfonate promoted chemoselective reactions of acyclic acetals with allyltrimethylsilane, allyltributyltin, a silyl enol ether, tributyltin hydride, trimethylsilyl azide and trimethylsilyl cyanide have been achieved in the p
ACTIVATION AND SYNTHETIC APPLICATIONS OF THIOSTANNANES. THIOALKOXYLATION OF ACETALS
Sato, Tsuneo,Otera, Junzo,Nozaki, Hitosi
, p. 1209 - 1218 (2007/10/02)
The Sn-S bonds in thiostannanes, BunSn(SPh)4-n, are activated towards acetals in the presence of BF3*OEt2.Acetals of various aldehydes and ketones are converted into the corresponding monothioacetals under mild conditions.Employment of α-enal acetals induces Michael addition to give synthetically useful γ-alkoxyally sulfides.
METHOXY(PHENYLTHIO)METHANE AS AN AMBI-EQUVIVALENT OF A METHOXY- OR PHENYLTHIOMETHYLENE 1,1-DIPOLE
Sato, Tsuneo,Okura, Shuji,Otera, Junzo,Nozaki, Hitosi
, p. 6299 - 6302 (2007/10/02)
Methoxy(phenylthio)methane undergoes electrophilic alkylation followed by nucleophilic allylation or propargylation which is dramatically changed depending on the Lewis acid employed providing a methoxy- or phenylthiomethylene 1,1-dipole synthon.
Organotin-Mediated Preparation of Monothioacetals
Sato, Tsuneo,Kobayashi, Takamitsu,Gojo, Tamehisa,Yoshida, Enji,Otera, Junzo,Nozaki, Hitosi
, p. 1661 - 1664 (2007/10/02)
Monothioacetals are obtained by treating the corresponding acetals with organotin thiophenoxides in the presence of BF3*OEt2.The reaction proceeds under mild conditions to provide the desired compounds with high selectivity.
Electrochemical Oxidation of 1-Phenylthio-1-trimethylsilylalkanes
Yoshida, Jun-ichi,Isoe, Sachihiko
, p. 631 - 634 (2007/10/02)
Electrochemical oxidation of 1-phenylthio-1-trimethylsilylalkanes in the presence of alcohol resulted in facile cleavage of the carbon-silicon bond and formation of the corresponding acetals.
