참여 물질

반응 단계

5-Nitroisophthalic acid (5 g) was converted to the mono allyl ester using one equivalent of allyl bromide (2 ml) using a similar method to that described in example 1. The required acid (2.7 g) was extracted from the organic phase with aqueous NaHCO3. The organic layer contained the di-allyl ester (2.7 g). The mono acid, 3-allyloxycarbonyl-5-nitrobenzoic acid, was obtained as a white solid. Nmr (CDCl3): 4.87 (d, 2H); 5.3-5.5 (q, 2H); 5.97-6.15 (m, 1H); 9.01 (t, 3H).
