REACTIONS OF EPOXY WITH OTHER FUNCTIONAL GROUPS AND THE ARISING SEC.HYDROXYL GROUPS

The primary attack by sulfur on aliphatic ketones proceeds readily and evenly at the activated methylene group, to give an a-thiolketone, which is then stabilized by reaction with

Mehltretter (26) oxidized glucose with platinum-charcoal catalyst under rigorous conditions at 50° and found that the primary hydroxyl group at carbon-6 can then be

Hydroxyl groups and even a single phenolic group, as in salicylic acid, do not interfere and give neutralization equivalents equal to the molecular weight.. However, in general,

Friedrich apparatus for determination of alkimide groups (N-ethyl and N-methyl). The reaction flask is heated by means of a suitable bath so that its contents may be raised

Substituting this luciferin’s 6-position hydroxyl group with an amino group, the resulting ami- noluciferin (aLuc) can form amide bond with a peptide, while retaining the

The reaction of dialkyl H-phosphonates (A) with aliphatic alcohols under mild conditions (lower alcohol excess and lower temperature) afforded the derivatives with different

During desiccation, both cultivars showed increase of oxidative stress (dehydroascorbate to ascorbate ratio, MDA, hydroxyl radicals) and antioxidant activity in the form of

The in vitro antioxidant activity was evaluated by trapping the ABTS and hydroxyl radicals as well as the inhibition of the enzyme acetyl-cholinesterase and hemolysis of erythrocytes
