In one aspect, the invention relates to compounds having the formula:

##STR00001##

where R.sup.1-R.sup.6, a, b, and Z are as defined in the specification, or a pharmaceutically acceptable salt thereof. These compounds have neprilysin inhibition activity. In another aspect, the invention relates to pharmaceutical compositions comprising such compounds; methods of using such compounds; and processes and intermediates for preparing such compounds.

The invention provides heterocyclic compounds with quaternary centers and methods of preparing compounds. Methods include the method for the preparation of a compound of Formula (II): ##STR00001##
comprising treating a compound of Formula (I): ##STR00002##
with a transition metal catalyst and under alkylation conditions as valence and stability permit.
