Alkyl-1,4-dihydropyridines on reaction with peracids undergo either extensive decomposition or biomimetic oxidation to A-alkylpyridinum salts (98JOC10001). However, A-methoxycarbonyl derivatives of 1,4- and 1,2-dihydro-pyridines (74) and (8a) react with m-CPBA to give the methyl tmns-2- 2>-chlorobenzoyloxy)-3-hydroxy-1,2,3,4-tetrahydropyridine-l-carboxylate (75) and methyl rran.s-2-(3-chlorobenzoyloxy)-3-hydroxy-l,2,3,6-tetrahydropyridine-l-carboxylate (76) in 65% and 66% yield, respectively (nonbiomimetic oxidation). The reaction is related to the interaction of peracids with enol ethers and involves the initial formation of an aminoepoxide, which is opened in situ by m-chlorobenzoic acid regio- and stereoselectively (57JA3234, 93JA7593). [Pg.285]

The modified Hantzsch condensation of nitroacetone, 2,l,3-benzoxadiazol-4-carboxaldehyde 253, and ( S,ZR)-Z-(3,5-dinitrophenylcarbonylamino)-2-methoxycarbonyl-l-methylethyl 3-aminocrotonate afforded a mixture of the two diastereomers that differ in configuration (S or R) at the C-4 position of the 1,4-DHP ring (DHP - dehydropeptidase) (Equation 49) <2004JME254>. [Pg.366]

The iminophosphoranes of methyl arylhydrazono acetates (338) possessing a keto function in an o-position afford l//-l,2,4-benzotriazepines (339) upon heating (Scheme 123). The yield depends on the substituents and solvents employed. Methoxycarbonyl-, 4-pyridyl-, and 3-pyridyl groups activate the carbonyl function and improve the yield. Reactions of alkyl ketones and aldehydes proved to be unsuccessful [91JCR(S)2],... [Pg.228]

The selenonium and sulfonium salts act as chiral alkylating agents for carbon nucleophiles under weakly basic conditions which avoid any ylide formation from the salt. When 2-methoxycarbonyl-l-oxoindane is treated with an (.S )-etliyl(methyl)phenylselenoniurn perchlorate, the (S)-2-methyl and (i )-2-ethyl derivatives are obtained with a low enantiomeric excess (Table 1).
