N-H ketoimines 3a-3v are readily prepared in high yield via organometallic addition to nitrites and isolated as corresponding bench-stable hydrochloride salts. Homogeneous asymmetric hydrogenation of unprotected N-H ketoimines 3a-3v using Ir-(S,S)-f binaphane as catalyst provides chiral amines 4a-4v in 90-95% yield with enantioselectivities up to 95% ee.
Iridium−Monodentate Phosphoramidite-Catalyzed Asymmetric Hydrogenation of Substituted Benzophenone N−H Imines
Homogeneous asymmetric hydrogenation of unprotected benzophenone N-H imines 1a-r using 1r-benzyl-N-methyl-MonoPhos as a catalyst provides chiral amines 2a-r in 80-96% yield with enantioselectivities up to 98% ee (18 examples) for ortho-substituted substrates.

The present invention relates to N-substituted heterocyclic derivatives of formula: ##STR1## processes for their preparation, and pharmaceutical compositions which contain them. The compounds according to the invention are non-peptide compounds which oppose the action of angiotensin II. The compounds according to the invention are thus useful in the treatment of cardiovascular disorders such as hypertension and heart failure.
