Elimination Reactions - result in the formation of a new π
... In an E2 reaction, a strong base removes a proton beta to the leaving group so long as there exists a conformation in which the proton is anti-periplanar to the leaving group. Where there are several such protons, several products are possible: ...

Amino Acids and Proteins
... The 20 amino acids that occur naturally in proteins differ in the identity of the R group bonded to the α carbon. The R group is called the side chain of the amino acid. The simplest amino acid, called glycine, has R = H. All other amino acids (R ñ H) have a stereogenic center on the ` carbon. As is ...

... (c) pre-esterification method. FFAs are first esterified to FAMEs using an acid catalyst, and then, transesterification is performed, as usual, by using an alkaline catalyst.5,10 Enzyme-based transesterification is carried out at moderate temperatures with high yields, but this method cannot be used ...

Synthetic applications of ortho esters
... In contrast to acetal derivatives of carbonyl compounds, ortho esters have found surprisingly limited use in organic synthesis [1]. Since ortho esters are among the few carboxylic acid protective groups that demonstrate a high level of stability toward strong nucleophiles and bases, most current app ...

When one nucleus attracts the electrons more strongly, the bonding electrons are located closer to one nucleus than the other. This creates an uneven distribution ...
