A highly efficient diastereoselective transfer hydrogenation of α-aminoalkyl α′-chloromethyl ketones catalyzed by a tethered rhodium complex was developed and successfully utilized in the synthesis of the key intermediates of HIV protease inhibitors. With the current Rh(iii) catalyst system, a series of chiral 3-amino-1-chloro-2-hydroxy-4-phenylbutanes were produced in excellent yields and diastereoselectivities (up to 99% yield, up to 99?:?1 dr). Both diastereomers of the desired products could be efficiently accessed by using the two enantiomers of the Rh(iii) catalyst.
CERTAIN ACYCLIC, ALICYCLIC, AROMATIC OR HETEROCYCLIC DERIVATIVES OF 3-BENZOYLAMINO-2-OXO- BUTYL-AMINO-CARBONYL-OXY-3-PROPANOIC ACIDS, ESTERS THEREOF, PHARMACEUTICAL COMPOSITIONS CONTAINING SAME AND THEIR ENKEPHALINASE INHIBITING PROPERTIES

Compounds of the formula STR1 wherein Y is oxygen or sulfur are disclosed. These compounds are useful as hypotensive agents due to their angiotensin converting enzyme inhibition activity and depending upon the definition of R 1 may also be useful as analgesics due to their enkepahlinase inhibition activity.
