Essentials of Organic Chemistry: For Students of Pharmacy, ...
This makes acetal or ketal formation a valuable means of protecting an aldehyde or ketone carbonyl from reaction with other reagents being used during a synthetic procedure. For instance, protection of a ketone group may be achieved by ...
2
Organic Chemistry: An Acid—Base Approach - Sayfa 866
Close examination of an acetal or ketal shows that the C=O unit is converted to a C(OR)2 unit. Another way to think about this is to recognize that an acetal or ketal does not undergo acyl addition and indeed is the product of acyl addition.

Novel Surfactants: Preparation Applications And ... - Sayfa 333
Hydrolysis of these compounds yields 1 mol of acetaldehyde and 2 mol of alcohol [which might be fatty alcohol alkoxylate, polyfalkylene glycol) or isobutanol]. C. Ketals Surfactants containing ketal bonds can be prepared from a long-chain ...

Anabolic Steroids and Making Them - Sayfa 24
15 20 Hydrolysis of the ketal with dil. hydrochloric acid gave ctiocholan-ll/3,17;9-diol-3-one, M.P. 171-173°. EXAMPLE 7. A mixture of 10.0 g. of prcgnan-ll/3,17a-diol-3,20- 5 dione, 10.0 g. of selenium dioxide, 150 ml. of ethylene glycol and 100 ...

Cracking the MCAT with CD-ROM - Sayfa 856
Dissolving an aldehyde or ketone in alcohol (with an acid catalyst) converts it first to a hemiacetal or hemiketal, which, on further reaction with alcohol, converts it to an acetal or ketal. The acetal and ketal moieties are unreactive in basic media ...

Palladium catalyzed cycloisomerizations with diasteromeric ... - Sayfa 9
The unreactivness of the modified trialklylsilyl ketals towards cyclization then lead us to propose increasing the steric bulk of the ketal groups. This can be done by alkyl subsitution on the phenyl ring to provide the o-tolyl ketal 17, and the ...

Natural and Synthetic Biomedical Polymers - Sayfa 225
Ketal hydrolysis at different rates in mildly acidic conditions as a function of the polymer hydrophobicity could lead to optimal release of the bioactive (e.g., therapeutic protein or vaccine) [18,88]. The ability to tune acetal/ketal degradation rates ...
