Bis-acceptor-substituted diazomethanes are most conveniently prepared by diazo group transfer to CH acidic compounds either with sulfonyl azides under basic conditions [949,950] or with l-alkyl-2-azidopyridinium salts [951] under neutral or acidic conditions [952-954]. Diazo group transfer with both types of reagents usually proceeds in high yield with malonic acid derivatives, 3-keto esters and amides, 1,3-diketones, or p, y-unsaturated carbonyl compounds [955,956]. Cyano-, sulfonyl, or nitrodiazomethanes, which can be unstable or sensitive to bases, can often only be prepared with 2-azidopyridinium salts, which accomplish diazo group transfer under neutral or slightly acidic reaction conditions. Other problematic substrates include amides of the type Z-CHj-CONHR and P-imino esters or the tautomeric 3-amino-2-propenoic esters, which upon diazo group transfer cyclize to 1,2,3-triazoles [957-959].

The reaction of nitriles with aldehydes in the presence of the catalyst 9 proceeds under neutral conditions to give the corresponding a,/3-unsaturated nitriles [8]. It is noteworthy that even acidic substrates tolerate the reaction. Thus, the reaction of ethyl cyanoacetate with 4-hydroxybenzaldehyde gave ethyl ( )-2-cyano-3-(4-hy-droxyphenyl)-2-propenoate (10) in 98% yield [7, 8]. [Pg.321]

An important feature of the present reaction is the chemoselective addition of activated nitriles to the CN triple bonds of nitriles in the presence of carbonyl groups, because of the strong coordination ability of nitriles toward metals. The iridium-catalyzed addition of ethyl cyanoacetate to 4-acetylbenzonitrile (30) gives ethyl (Z)-3-(4-acetylphenyl)-3-amino-2-cyano-2-propenoate (31, 59%) chemoselec-tively, while the same reaction promoted by a conventional base such as AcONH4 and NaOH gives ethyl 2-cyano-3-(4-cyanophenyl)-2-butenoate (32) ( Z= 55 45) [20].

X = S) to DMAD to yield dimethyl 5-phenylisothiazole-3,4-dicarboxylate is much slower than the corresponding oxathiazolone (282) (X = O) <89JCS(Pl)2489>. The thermal decomposition of ethyl 2-azido-3-(3-azido-2-thienyl)propenoate (283) results in the formation of ethyl 5-cyano-isothiazole-3-carboxylate (284) together with the thienopyridazine (285) <84JCS(P1)915>. The addition of benzyne to 3,4-dimethyl-1,2,5-thiadiazole (286) gives 3-methyl-1,2-benzisothiazole <82CC299>. [Pg.366]

Reaction of ketene dithioacetals 260 with thioamides gave 5-substituted 2-methyl(phenyl)-6-methylthio-4-thioxopyrimidine (262) (92H1573). The reaction mechanism involves the addition of the thioamide to the ketene dithioacetal 260 to afford 2-cyano-3-methylthio-3-thioamido-propenoni-trile or -propenoate intermediate, which cyclizes in situ by site-selective nucleophilic attack of the sulfur on the cyano group to give 6-imino-l,3-thiazine 261, which rearranged to 262 (Scheme 84).
