Synthesis of pyrrolidines and pyrrolidinones by the rhodium complex catalyzed cyclization of unsaturated amines
摘要:
N-Allylic arylamines react with carbon monoxide, sodium borohydride, 2-propanol, and catalytic amounts of the zwitterionic complex eta-6-C6H6BPh3-Rh(COD)+ (1), to form pyrrolidines as the main products in most cases. Pyrrolidinones result from N-allylic alkylamines. An alternate route to the lactams from N-allylic alkylamines involves synthesis gas instead of CO/NaBH4, together with the dual catalytic system 1/[Ru(CO)3Cl2]2. Complementary to the N-allylic arylamine route to pyrrolidines with NaBH4 and 1 is the use of synthesis gas, 1, and 1,4-bis(diphenylphosphino)butane.

A palladium‐catalyzed N‐alkylation of anilines with tertiaryamines that occurs under heterogeneous transfer‐hydrogenation conditions has been developed (see scheme). This protocol of transamination, which uses a relatively cheap and easily recyclable heterogeneous catalyst, can be efficiently applied to different substrates and is suitable for large‐scale preparations.

[reaction: see text] A simple, selective, rapid, and efficient procedure for the synthesis of secondary amines from the reductive alkylation of either aliphatic or aromatic nitro compounds and the corresponding amines is reported. Ammoniumformate is used as the hydrogen source and Pd/C as the hydrogen transfer catalyst. The reaction is carried out at room temperature. The rate differences for the preferential

Diversity: A range of substituted 2‐alkylquinolines can be prepared in a general and efficient synthetic approach that employs mild reaction conditions (see scheme). The synthesis is based on a sequential palladium‐catalyzed CN and CCbondformation, followed by palladium‐catalyzed aromatization, and results in the formation of the desired compounds in one step.
