ChemInform Abstract: New Generation of Enantiomerically Pure N‐α‐Carboxyalkylglycolurils.

Abstract

α-Ureidoalkylation of N-carbamoyl-α-amino acids (II) and (VI) with imidazolidinones (I) and (V) affords a new type of glycolurils which contain N-alkyl, phenyl and (S)-α-carboxyalkyl groups in various combinations. The yields and diastereoselectivity in the syntheses of glycolurils are affected by both the amount of HCl added as well as the structures of the educts. Increasing the amount of HCl increases the diastereoselectivity but decreases the yield of the glycolurils, due to an increase of the yield of hydantoin by-products. Attempts to separate the mixtures of diastereomers are unsuccessful. - (BARANOV, V. V.; KRAVCHENKO*, A. N.; BELYAKOV, P. A.; MAKHOVA, N. N.; Mendeleev Commun. 18 (2008) 2, 96-98; Zelinsky Inst. Org.

“…The flesh fly fauna of Croatia has been poorly studied. The earliest data were published between the mid-19 th century and the beginning of the 20 th century (Schiner 1862; Brauer and Bergenstamm 1891; Strobl 1893, 1900, 1904; Böttcher 1912, 1913; Langhoffer 1920; Rohdendorf 1937), whereas the first studies more specifically focused on Croatian flesh flies were undertaken before and during World War II by Baranov (1928, 1929, 1930, 1931, 1938, 1939, 1940, 1941a, 1941b, 1942, 1943), who provided information on the general morphology and taxonomy of Croatian Sarcophaginae as well as descriptions and identification keys. Baranov’s work was continued by Strukan (1964, 1967, 1968, 1970), and further data were added after the breakup of Yugoslavia by Povolný and Znojil (1994), Rucner (1994), Pape (1996), Povolný and Znojil (1998, 1999), Pape (2004), Whitmore (2011) and Whitmore et al (2013).…”
