Notes:
We have synthesized three series of co-oligomers of the following type: where Z represents the carbobenzoxy blocking group and the subscripts can assume various small integral values.The first series includes the dimer (a = 1, b = 0), trimer (a = 1, b = 1) and pentamers (a = 2, b = 1) and was prepared using the p-nitrophenyl ester technique. The second series is made up of dimer (n = 1, m = 0), trimer (n = 1, m = 1), pentamer (n = 2, m = 1), heptamer (n = 3, m = 1) and undecamer (n = 5, m = 1) and was prepared using mixed anhydrides and modified azide reactions. Lastly, the third series is composed of an octamer (w = 0, x = 3, y = 2) a decamer (w = 0, x = 3, y = 4) and an undecamer (w = 2, x = 3, y = 2). This group of compounds was synthesized by using p-nitrophenyl ester and modified azide reactions.
