5-Bromo-1,8-naphthyridin-2-ami

Synthesis of (2S, 4S, 5S)-5-(t-Butoxycarbonylamino)-4-(t-Butyldimethylsilyloxy)-2-Isopropyl-7-Methyl Octanoic Acid

to replace combinattons of leucme coupled with valine in pepttde sequences. The preparation described is the final method developed, after many early less successful attempts. The synthesis mvolves (Fig. 1 ) the coupling of 1-bromo-5-methyl-2-hexene 3 and N
