Our stock solutions contain retinoids dissolved in either dimethy sulfoxide (DMSO) or absolute ethanol. Care must be taken to ensure that proper controls are performed in order to exclude any effects of the vehicle used to deliver the retinoid on the samples being examined... 

Carbanions derived from optically active sulfoxides react with esters, affording generally optically active )S-ketoesters ° . Kunieda and coworkers revealed that treatment of (-t-)-(R)-methyl p-tolyl sulfoxide 107 with n-butyllithium or dimethy-lamine afforded the corresponding carbanion, which upon further reaction with ethyl benzoate gave (-l-)-(R)-a-(p-tolylsulfinyl)acetophenone 108. They also found that the reaction between chiral esters of carboxylic acids (R COOR ) and a-lithio aryl methyl sulfoxides gave optically active 3-ketosulfoxides The stereoselectivity was found to be markedly influenced by the size of the R group of the esters and the optical purity reached to 70.3% when R was a t-butyl group.

A truly homogeneous process is attractive from a technical standpoint, although it has not been commercialized. Several solvents permit nondegradative dissolution of the cellulose, e.g., dimethyl formamide initrogen tetroxide, dimethyl sulfoxide-formaldehyde, dimethy-lacetamide-lithium chloride, and A-methylmorpholine oxide. Cellulose in solution can be esterified uniformly and directly to the desired degree of substitution [18 22].
