Abstract: The present invention provides process useful for the preparation of intermediates which are useful in the preparation of amino acids useful in preparing peptide receptor modulators, for example agonists or partial agonists of such peptide receptors. Such peptide receptor modulators include, for example glucagon like peptide-1 receptor modulators which are useful for the amelioration of the diabetic condition.

Abstract: Compounds of the formula ##STR1## and pharmaceutically acceptable salts thereof wherein: A is a bond or --OCH.sub.2 --, where the oxygen is linked to R.sup.1 ;B is --CH.sub.2 -- or when R.sup.3 is hydrogen, B may be --CH.sub.2 O-- where the oxygen is linked to the phenyl ring;R.sup.1 is an aryl group;R.sup.2 is hydrogen or lower alkyl;R.sup.3 is hydrogen; or R.sup.2 and R.sup.3 together form the group --CH.sub.2 CH.sub.2 --; andR.sup.4 is --SO.sub.3 H, --P(O.sub.2 H)R.sup.5, --P(O.sub.2 R.sup.5')R.sup.5, --PO.sub.3 H.sub.2, --PO.sub.3 HR.sup.5' or --PO.sub.3 (R.sup.5').sub.2 where R.sup.5 and R.sup.5' are independently lower alkyl. These compounds are beta.sub.3 adrenergic receptor agonists and are useful, for example, in the treatment of diabetes, obesity, achalasia, and gastrointestinal diseases.
