A one-pot synthesis of N-alkylaminobenzenes from nitroaromatics: reduction followed by reductive amination using B10H14

N-Alkylaminobenzenes were prepared in a simple and efficient one-pot synthesis by reduction of nitrobenzenes followed by reductive amination with decaborane (B10H14) in the presence of 10% Pd/C.

Synthesis of indole-3-carboxylic acid derivatives by Pd(0)-catalyzed intramolecular α-arylation of β-(2-iodoanilino) esters

(Chemical Equation Presented) β-(2-Iodoanilino) esters undergo intramolecular α-arylation in the presence of Pd(PPh3) 4 and potassium phenoxide. The reaction is a useful methodology for the preparation of indole-3-carboxylic acid ester derivatives.

Chemo- and diastereoselective reduction of β-enamino esters: A convenient synthesis of both cis- and trans-γ-amino alcohols and β-amino esters

Convenient procedures for the chemo- and diastereoselective reduction of b-enamino esters 1 are described. Both cis- and trans-γ-amino alcohols 2 or b-amino esters 3 can be prepared by reduction of b-enamino esters 1, readily available starting materials, with the use of inexpensive reagents Na/i-PrOH or NaHB(OAc)3/AcOH, respectively, and the appropriate reduction conditions. The mechanisms and diastereoselectivities for the reductions are discussed. The relative configurations and conformations of the diastereoisomeric γ-amino alcohols 2 and β-amino esters 3 obtained are established by 1H and 13C NMR study and unequivocally set by their cyclic derivatives tetrahydro-1,3-oxazines 4.
