Efficient synthesis of α-amino secondary amides by direct aminocarbonylation of N-Boc-imines using carbamoylsilane as an amide source

, (2020)
A novel and practical procedure for the preparation of α-amino secondary amides by the aminocarbonylation of N-Boc-imines using carbamoylsilanes bearing methoxymethyl group as secondary amides source is presented herein. The protocol tolerates N-Boc-imines bearing different groups, including aryl, double bond conjugated aryl, heteroaryl and aliphatic groups. The reactions provide good to excellent yields of the products under mild and catalysts-free conditions. The electronic property and the steric hindrance of substituent on the N-Boc-imines affect the reaction.

It is shown how imidazolinones are reduced by trichlorosilane in a highly enantioselective fashion when treated with a novel Lewis base organocatalyst that is based on a 2,2′-bispyrrolidine core. Under mild reaction conditions and with low catalyst loading the hydrosilylation reaction provides a broad range of chiral imidazolidinones with various structural motifs including sterically demanding substituents, alkyls and aryls.

Intermediate compounds for the preparation of mirtazapine and obtention methods thereof. A method is described for obtaining (±)-3-phenyl-1-methylpiperazine, an important intermediate for obtaining mirtazapine, which is based on imposing a cyclation reaction, in the presence of a reducing agent, on new compounds of general formula (I) in which Z is a leaving group capable of undergoing a nucleophylic displacement. A method is also described for obtaining the new compounds of formula (I).
