This work describes the use of cheap, safe, and easy-to-handle hydrosilatrane as the reductant in direct reductive amination reactions. This efficient method enables a facile, metal-free access to secondary and tertiaryaminesfrom a wide range of aldehydes and ketones, with the synthesis of tertiaryamines requiring no additives at all. This reaction demonstrates excellent functional group tolerance

use of mixed aliphatic organozinc reagents in the multicomponent Mannich reaction is described. A large variety of primary, secondary, and tertiary organozinc reagents, secondary amines and aromatic or aliphatic aldehydes could be used for the straightforward preparation of densely substituted amines. The three-component reaction could additionally be performed starting from alkyl halides under reductive
