A −CH2CH:C+NR2 synthon: Novel preparations of 1,3-disubstituted allylamines and of 1,2-diaryl pyrroles
摘要:
1-(3-Morpholinoprop-2-enyl)benzotriazole (1) is a useful synthon of the type [(CH2)-C---CH=C(+)NR(2)] as demonstrated by the preparation of allylamines 4. It can also provide a [(+ -) CH-CH=CH+] fragment for the synthesis of 1,2-diarylpyrroles 6.

eliminated to form products of type Bt-CHR-NR′R″. The latter are versatile intermediates for the preparation of primary, secondary, and tertiary amines and in the alkylation of hydroxylamines, hydrazines, amides, thioamides, and sulfonamides. Polyfunctional amines and other polyfunctional compounds can also be prepared, and they enable significant extending of Mannich reaction.
