Liu, You-Chen,Reddy, Daggula Mallikarjuna,Chen, Xin-An,Shieh, Yi-Chen,Lee, Chin-Fa
, p. 2542 - 2552 (2020/04/27)
In synthetic chemistry, the protection of aldehydes and ketones is crucial during multistep synthesis of complex molecules. Organic chemists have paid substantial attention to the synthesis of 1,3-oxathiolanes and 1,3-oxathianes because of their considera

, p. 5839 - 5844 (2013/10/21)
Various aromatic aldehydes on reaction with 2-mercaptoethanol provided an unanticipated product, bis(2-hydroxyethyl)dithioacetals (3) as the major product along with the expected product 1,3-oxathiolanes (4) in the presence of 0.05 equiv amount of nickel(
Tantalum(V) chloride-silica gel: An efficient catalyst for conversion of carbonyl compounds to 1,3-oxathiolanes
Chandrasekhar,Prakash, S. Jaya,Shyamsunder,Ramachandar
, p. 3127 - 3131 (2007/10/03)
A variety of carbonyl compounds can be easily converted to the corresponding 1,3-oxathiolanes in the presence of a catalytic amount of tantalum(V) chloride [TaCl5] on silica gel in dichloromethane. Mild reaction conditions, efficiency, high yie
Silica gel-supported polyphosphoric acid (PPA/SiO2) as an efficient and reusable catalyst for conversion of carbonyl compounds into oxathioacetals and dithioacetals
Aoyama, Tadashi,Takido, Toshio,Kodomari, Mitsuo
, p. 2307 - 2310 (2007/10/03)
A simple and efficient method for the conversion of carbonyl compounds to oxathioacetals and dithioacetals by using polyphosphoric acid supported on silica gel (PPA/SiO2) as an acid catalyst have been developed. PPA/SiO2 is easily re
Indium trifluoromethanesulfonate as a mild and chemoselective catalyst for the conversion of carbonyl compounds into 1,3-oxathiolanes
Kazahaya, Kiyoshi,Hamada, Nao,Ito, Shinya,Sato, Tsuneo
, p. 1535 - 1537 (2007/10/03)
An efficient method for the preparation of 1,3-oxathiolanes from aldehydes and ketones with 2-mercaptoethanol in the presence of a catalytic amount of indium trifluoromethanesulfonate is reported.
LiBF4 catalyzed chemoselective conversion of aldehydes to 1,3-oxathiolanes and 1, 3-dithianes
Yadav,Reddy,Pandey
, p. 238 - 239 (2007/10/03)
Lithium tetrafluoroborate is found to be an efficient catalyst for the chemoselective protection of both aromatic and aliphatic aldehydes as 1,3-oxathiolanes and 1,3-dithianes under mild reaction conditions. Due to the neutral reaction conditions, this me
Amberlyst 15 as a mild, chemoselective and reusable heterogeneous catalyst for the conversion of carbonyl compounds to 1,3-oxathiolanes
Ballini,Bosica,Maggi,Mazzacani,Righi,Sartori
, p. 1826 - 1829 (2007/10/03)
The synthesis of 1,3-oxathiolanes from carbonyl compounds has been performed in good yields using Amberlyst15 as a convenient, reusable, heterogeneous catalyst. The procedure can be applied for the chemoselective protection of aldeydes in the presence of
SILICON IN SYTHESIS-17 CHLROMETHYL(TRIMETHYLSILYL)LITHIUM-A NEW REAGENT FOR THE DIRECT CONVERSION OF ALDEHYDES AND KETONES INTO α,β-EPOXYTRIMETHYLSILANES
Burford, Clifford,Cooke, Frank,Roy, Glenn,Magnus, Philip
, p. 867 - 876 (2007/10/02)
Treatment of chloromethyltrimethylsilane 1 with sec-BuLi at -78 deg produces chloromethyl(trimethylsilyl)lithium 4.Treatment of 4 with a wide range of aldehydes and ketones gives α,β-epoxytrimethylsilanes 5-28, which on acidic hydrolysis give homologated aldehydes.
