A cascade Aza-Cope/Aza-prins cyclization leading to piperidine derivatives

The cascade aza-Cope/aza-Prins cyclization of homoallylamines to give substituted piperidines has been explored. The use of glyoxalic acid as the carbonyl component afforded bicyclic structures as a result of the internal carboxylate anion trapping the intermediate cation. The unimolecular bis-, tris-, and tetrakis(homoallylamine)s efficiently delivered the appended bis-, tris- and tetrakis(piperidine-4-ol)s (tripod and crucifix shape, respectively) as new entities. The latter compound served as an excellent ligand in the Suzuki-Miyaura cross-coupling reaction to synthesize incrustoporin. The cascade aza-Cope/aza-Prins cyclization of homoallylamines to give substituted piperidines is described. A unimolecular tetrapiperidine derivative, which resulted from this strategy, was employed as a ligand in the Suzuki-Miyaura cross-coupling reaction of an α-iodobutenolide with an arylboronic acid in an efficient synthesis of incrustoporin and its analogues.

Diastereoselective Ti-mediated preparation of bicyclic aminocyclopropanes from N-alkenyl amides

Intramolecular Ti-mediated alkene-amide couplings of a range of N-alk-3-enyl amides fitted with a substituent at the homoallylic position are described. CF3-substituted compounds are suitable substrates and bicyclic aminocyclopropanes bearing a

Stereoselective synthesis of pyrrolidines and pyrrolizidines by intramolecular carbolithiation

Methods for the preparation of substituted homoallylic amines and their conversion to pyrrolidines or pyrrolizidines are described. N-Alkylation of a variety of homoallylic secondary amines with (tributylstannyl)methyl methanesulfonate and subsequent tinlithium exchange, generates organolithium species that undergo intramolecular carbolithiation (anionic cyclization). High stereoselectivities in the cyclization, particularly for the formation of 2,4-disubstituted pyrrolidines, are obtained.

Stereoselective anionic cyclizations to pyrroldines

Cyclization of α-amino-organolithiums onto unactivated alkenes results in the formation of 2,4-disubstituted pyrrolidines with high selectivities in favour of the cis isomers. The use of the α-methylbenzyl chiral auxiliary on the nitrogen atom gives rise

Synthesis of azetidines by electrophilic selenium-induced cyclization of homoallylic benzylamines

Homoallyl benzylamines prepared by allylation of the corresponding N-benzylimines, have been subjected to a selenium-induced cyclization under various conditions. At room temperature. the 4-exo and the 5-endo modes are competitive. In acetonitrile, the azetidine has been isolated as the major cyclization product, especially for homoallylamines derived from ketimines. With an excess or selenium reagent, 3-halopyrrolidines have been obtained.

Addition of Allylboronates to Schiff Bases and to Oximes

Clean addition of allylboronates of Type 3 to Schiff bases 2 leads to the secondary homoallylamines 4.Analogous addition to the oximes 9 results in the formation of the hydroxylamines 13.The latter allow the generation of the primary homoallylamines 14.
