This invention provides a series of substituted propanamines which are useful in treating a physiological condition which may be modulated by an increase in growth hormone. This invention also provides methods for the treatment of such physiological conditions which comprise administering a growth hormone secretagogue as described in the present invention in combination with growth hormone releasing hormone.

For the first time we have been able to employ enantiopure 1,2‐aminoalcohols derived from abundant amino acids in C−C bond‐forming hydrogen‐borrowing alkylation reactions. These reactions are facilitated by the use of the aryl ketone Ph*COMe. Racemisation of the amine stereocentre during alkylation can be prevented by the use of sub‐stoichiometric base and protection of the nitrogen with a sterically
N-Tritylamino acids activated with DCC/HOBt, were coupled with various aminoacid derivatives without racemization. The tritylgroup was split off quantitatively in 10% CCl3COOH monohydrate or CH2ClCOOH in CH2Cl2. Under these conditions detritylation of N-Trt-Trp-Gly-NH2 proceeds without formation of an oxindole derivative and side alkylation products, even in the absence of a scavenger. Dipeptide
