Of imines

Enamines derived from ketones are allylated[79]. The intramolecular asymmetric allylation (chirality transfer) of cyclohexanone via its 5-proline ally ester enamine 120 proceeds to give o-allylcyclohexanone (121) with 98% ee[80,8l]. Low ee was observed in intermolecular allylation. Similarly, the asymmetric allylation of imines and hydrazones of aldehydes and ketones has been carried out[82]. [Pg.308]

Carbinolamines are formed by nucleophilic addition of an amine to a carbonyl group and are intermediates in the for mation of imines and enamines Carbocation (Section 4 8) Positive ion in which the charge re sides on carbon An example is tert butyl cation (CH3)3C Carbocations are unstable species that though they cannot normally be isolated are believed to be intermediates in certain reactions... [Pg.1278]

Peracid oxidation of imines is the most general synthesis of oxaziranes (Section 5.08.4.1.1). Other peroxides and metal catalysis have also been employed. [Pg.36]

A number of imine derivatives have been prepared as amine protective groups, but few of these have seen extensive use. The most widely used are the benzylidene... [Pg.368]

The formation of imines mkes place by a mechanism that is the reverse of the hydrolysis. Preparative proc ures often ensure completion of the reaction by removing water as it is formed by azeotropic distillation or by the use of an irreversible dehydrating agent. [Pg.460]

The dienophilic character of imines parallels that of carbonyl compounds Consequently, electron deficient imtnes are the most reactive dienophiles of this class, particularly those having C perfluoroalkyl [5, 146, 150, 228], /V-acyl [/2i5 127], or A/-sulfonyl groups [148, 229 230]... [Pg.870]

Carbinolamines are formed by nucleophilic addition of an amine to a carbonyl group and are intermediates in the formation of imines and enamines. [Pg.1278]

The alkylation of imines by an alkyl halide to give an iminium salt will be illustrated by selected reactions over a period of years. A more complete survey is available (88). Decker and Becker (89) prepared a number of iminium salts (91, for example) by mixing methyl iodide and aromatic imines in benzene. 2,5-Dimethyl-2-pyrroline (92) has been alkylated and the... [Pg.79]

Analogous compounds with a secondary amino group (a,j8-unsaturated secondary amines) can, in principle, exist in either the form of imines (6) or the tautomeric form of enamines (7). As they practically occur and react in the former structure, it is more convenient to use the group designation imines. ... [Pg.254]

In both cases, the hydride ion approaches the double bond from the sterically more accessible side of the molecule. Reduction of imines by metals and acids, electrolytically or by formic acid gives saturated secondary amines (38,255). [Pg.289]
