A thioamide of isonicotinic acid has also shown tuberculostatic activity in the clinic. The additional substitution on the pyridine ring precludes its preparation from simple starting materials. Reaction of ethyl methyl ketone with ethyl oxalate leads to the ester-diketone, 12 (shown as its enol). Condensation of this with cyanoacetamide gives the substituted pyridone, 13, which contains both the ethyl and carboxyl groups in the desired position. The nitrile group is then excised by means of decarboxylative hydrolysis. Treatment of the pyridone (14) with phosphorus oxychloride converts that compound (after exposure to ethanol to take the acid chloride to the ester) to the chloro-pyridine, 15. The halogen is then removed by catalytic reduction (16). The ester at the 4 position is converted to the desired functionality by successive conversion to the amide (17), dehydration to the nitrile (18), and finally addition of hydrogen sulfide. There is thus obtained ethionamide (19)... [Pg.255]

The mechanistic details of the cleavage of (S—C) bonds in ionized sulfides, such as 111-+113 constitute a challenging problem. Some insight was obtained from a CA spectroscopy study49 and from the investigation of 2H-labelled precursors50,51 For ionized ethyl methyl sulfide 111 it was concluded from the CA spectra that in...

More recently, 4-methylbenzyl 25 and 4-methoxybenzyl (Mob) protection17 was proposed for the selenol group. The 4-methylbenzyl group is introduced by reacting selenocysteine with a-bromo-p-xylene following essentially the procedure for the preparation of the related cysteine derivative. 25 This type of protection is applied in combination with the Boc/Bzl strategy and its removal is achieved by HF treatment in the presence of 15% anisole and 2.5% ethyl methyl sulfide at 0°C in one hour. Unfortunately, experimental details were not reported by Oikawa et al. 25 ... [Pg.216]
