A series of transition-state analogues having heterocyclythio C-termini has been synthesized and evaluated for inhibition of human renin. Addition of mercaptoheterocycles to a chiral Boc-amino epoxide intermediate led, after several steps, to the target [(2R,3S)-3-(BocPheHis-amino)-4-cyclohexyl-2-hydroxy-1-butyl]thio derivatives. Oxidation of the thioether
