Carboxylation with CO2 via brook rearrangement: Preparation of α-hydroxy acid derivatives

, p. 14 - 17 (2014/01/23)
In the presence of CsF, a wide range of α-substituted α-siloxy silanes were carboxylated under a CO2 atmosphere (1 atm) via Brook rearrangement. A variety of α-substituents including aryl, alkenyl, and alkyl groups were tolerated to afford α-hydroxy acids in moderate-to-high yields. One-pot synthesis from aldehydes using PhMe2SiLi and CO 2 was also possible, providing α-hydroxy acids without the isolation of an α-hydroxy silane.
Cyclic alkyl substituted glycolides and polylactides therefrom

Page/Page column 6, (2008/06/13)
Cyclic alkyl, particularly cyclohexyl, substituted glycolides and polylactides are described. The polylactides have a high glass transition temperature and improved clarity.

Concellon, Jose M.,Bernad, Pablo L.,Perez-Andres, Juan A.
, p. 1409 - 1412 (2007/10/03)
A rapid and effective diiodomethylation of carbonyl compounds using SmI2 and iodoform is described. Transformations of the obtained diiodoalcohols 2 into α-iodoaldehydes 5 and α-hydroxyacids 6 is also reported.
