hMC4R. Potent cis-(2S,4R)-pyrrolidine based MCR agonists (35a-g) were subsequently developed by means of this designapproach. A SAR study directed toward probing the effect of the two chiral centers in the pyrrolidine ring on biological activity revealed the importance of the (S) absolute configuration at the 2-position for binding affinity, agonist potency, and receptor selectivity. Among the four

N-Boc 3-hydroxypyrrolidine 1 undergoes directed C-lithiation at C5 and not, as previously reported, at C2; the resulting dilithiated intermediate 6 has been trapped by a range of electrophiles to give 2-substituted 4-hydroxypyrrolidines 7.
The present invention relates to a compound of the following formula 1, pharmaceutically acceptable salt and isomer thereof effective as agonist of melanocortin receptor, and an agonistic composition of melanocortin receptor comprising the same as active ingredient.
