The conformation of the title compound 1 is deduced from 'H NMR evidence. The stable conformations of u-Temp-(L-Ala) NBMe in MeCN are shown to be distorte 8 -0tBu and a-Temp-L-Ala-L-Phe-L-Lys(cBoc)-L-Lys(&-Boc)ehelices with a bifurcated hydrogen bond. In the accompanying communication we have repor
