2-Acetylbenzoic acid

Several syntheses of tetrabenzoporphyrin complexes make use of similar template strategies to those used in phthalocyanine synthesis, so they will be discussed here. An isoindole has been found to undergo a very complex series of reactions promoted by a range of metal ions in refluxing 1,2,4-trichlorobenzene to produce tetrabenzoporphyrin complexes (Scheme 55).240 In contrast, an extremely simple synthesis of tetrabenzoporphyrin can be achieved from 2-acetylbenzoic acid, using zinc as templating metal (equation 44).241... [Pg.194]

Spiroquinazolines (114) can be obtained from hydrazides 104 and cyclohexanone (X = CH2) or l-methyl-4-piperidone (X = NMe).176 y-Ketocarbox-ylic acids as 2-acetylpropionic acid (115) form the condensed quinazolones 116 or 117, depending on the substitution of the ring and hydrazine nitrogens. With 2-acetylbenzoic acid (118), the analogous tetracyclic derivative 119 is obtained176,177 (Scheme 20). Half a mole of hydrazine hydrate with one mole... [Pg.150]
