For unsymmetrical diisonitrile 101, reaction with both glutaric acid and octanedioic acid, and isobutyraldehyde and isopropylamine afforded macrocycle 105a and 105b, respectively, in reasonable yield. Reaction of 101 with 1,6-diaminohexane, acetic acid and isobutyraldehyde yielded 106 in a very acceptable 51% yield (Scheme 18). 

Cognate preparations. Suberic acid (octanedioic acid). Heat a mixture of octanedinitrile (Expt 5.157) with 15 times its weight of 50 per cent sulphuric acid by weight under reflux for 10 hours. The acid crystallises out on cooling. Filter off the suberic acid upon a sintered glass funnel, and recrystallise it from acetone m.p. 141-142 °C. The yield is 90 per cent of the theoretical. 

A dicarboxylic acid is named as a dioic acid. The carboxyl functions are the terminal carbons of an eight-carbon chain H02C(CH2)6C02H is octanedioic acid. It is not necessary to identify the carboxylic acid locations by number because they can only be at the ends of the chain when the -dioic acid name is used.
