Eco-friendly synthesis of novel thiohydantoin-type sulfur-containing imidazolinone derivatives from glycine ester
Gümü?, Mustafa Kemal,Elemes, Yiannis
, (2018)
[Figure not available: see fulltext.] Imino derivatives of glycine ester were prepared from methyl glycinate by the known procedure and then they reacted with several amines under microwave irradiation without solvent that gave the corresponding glycine a
Synthesis of sulfur containing dihydro-pyrrolo derivatives and their biological evaluation as antioxidants

The 1,3-dipolar cycloaddition to N-phenylmaleimide of azomethine ylides, generated in situ from sulfanyl-substituted imines of glycine esters, yields 5H-dihydro-pyrrolo products with syn diastereoselectivity. The syn (major) and anti (minor) products were

Krishnaswamy,Govande,Gumaste,Bhawal,Deshmukh
, p. 2215 - 2225 (2007/10/03)
An efficient use of triphosgene, as an acid activator, for the synthesis of substituted azetidin-2-ones via ketene-imine cycloaddition reaction using various acids and imines have been described.
Stereospecific Synthesis of N--α,β-Didehydroamino Acid Methyl Esters, New Synthons in the Synthesis of α-Amino Acids
Cativiela, Carlos,Villegas, Maria D. Diaz de
, p. 497 - 506 (2007/10/02)
N--α,β-didehydroamino acid methyl esters 4a-c have been prepared with total geometric selectivity from easily accesible β-hydroxyamino acids through N--β-hydroxyamino acid methyl esters 3a-c as intermediates.The (E)-isomers can be easily converted into the corresponding (Z)-isomers in the presence of a catalytic amount of titanium (IV) chloride. Key words: Stereospecific dehydration, stereoisomers, didehydroamino acids, amino acids, E-Z isomerization
Unique zeolite-catalyzed synthesis of nitroketene S,N-acetals
Indrasena Reddy,Bhawal, Baburao M.,Rajappa, Srinivasachari
, p. 2101 - 2108 (2007/10/02)
Dimethyl carbonimidodithioates (4a-g, 7a-c) derived from various primary amines and amino acid esters [glycine, (L)-alanine and (L)-phenylalanine] have been condensed with nitromethane in the presence of the rare-earth exchanged zeolite RE(70%)Na Y to give the S,N-acetals (5a-g, 8a-c). Mercuric chloride catalyzed hydrolysis of these (8a-c) has led to the nitroacetyl derivatives (9a-c). The glycine derivative (7a) gives a dimeric product (11) when heated alone with the zeolite.
