A new method for regioselective synthesis of 2-substituted 1-(methoxycarbonyl)-1,2-dihydropyridines

2-Substituted 1,2-dihydropyridines including an optically active one were regioselectively prepared from 2-substituted piperidines through three intermediates, that is, (a) 1,2,3,4-tetrahydropyridines, (b) 5-bromo-6-methoxypiperidines, and (c) 1,2,3,6-tetrahydro- 6-methoxypyridines.     

A new method of synthesis of 6-aminopurines

Conclusions A method has been developed for obtaining 6-aminopurines by the direct amination of hypoxanthine and its derivatives with amides of phosphoric acid.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 4, pp. 953–955, April, 1970.     

A new method for the synthesis of dichlorophosphines

A new method for the synthesis of alkyldichlorophosphines by chlorination of alkylphosphines with phosphorus pentachloride under mild conditions is described.     

A new synthesis of (+)- and (-)-cherylline

A new and concise synthesis of enantiopure antipodes of alkaloid cherylline has been devised. The synthetic strategy relies upon the reduction of a diversely and polyprotected diarylenamine bearing a chiral auxiliary. Separation of diastereopure intermediates, concomitant deprotections and intramolecular reductive amination complete the synthesis of the natural (S)-enantiomer and of the unnatural (R)-configured antipode.     

A new general method for synthesis of ketene dithioacetal

Dithioacetals ($\text{1}$) were treated with n-butyllithium and 2,2′-dipyridyl disulfide to give ketene dithioacetals ($\text{3}$) in high yields, which constituted a new efficient synthetic method for the latter compounds.     

A new method for the synthesis of 5-amidinobarbiturates

The reactions of 5-[arylamino(methylthio)methylene]pyrimidine-2,4,6(1H,3H,5H)-triones with different aliphatic and aromatic amines were studied. A series of 5-amidinobarbiturates was synthesized. A new and preparatively convenient method for their synthesis appropriate for the use in the combinatorial chemistry was developed. Published in Russian in Izvestiya Akademii Nauk. Seriya Khimicheskaya, No. 8, pp. 1557–1563, August, 2007.     

A new convenient method for the synthesis of cardiolipin

A novel dichlorophosphate coupling method is developed for the synthesis of the title compound. O-Chlorophenyl dichlorophosphate can be used as a mild phosphorylating reagent to effectively couple with optically active 1,2-O-diacyl-sn-glycerol and 2-O-protected glycerol to assemble cardiolipin bearing different fatty acid chains.     

A new method for the synthesis of N-substituted pyrroles

<正>An unexpected reaction of 10-bromomethyl-12-oxocalanolide A(2) with primary amine was demonstrated and studied. Consequentially,a new method for the preparation of N-substituted pyrroles starting fromγ-halo-α,β-unsaturated ketone was presented.     

A new method for the synthesis of monoalkyl-substituted cyclobutanes

A new method for the synthesis of 3-aryl-6-(2-pyrrolyl)pyridazines

A new method for the synthesis of 3-halo-6-(N-tosyl-2-pyrrolyl)pyridazine 7 was developed. Suzuki cross-coupling reactions of 7 with arylboronic acids and in situ de-tosylation gave a variety of novel 3-aryl-6-(2-pyrrolyl)pyridazines. It found that protection of the pyrrolyl moiety was necessary for efficient coupling reaction.     

A new method for the synthesis of levulinic acid

A two- step method is described for the synthesis of levulinic acid from ethyl acetoacetate and ethyl chloroacetate in 70% yield.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 2, pp. 474–475, February, 1990.
