Novel thiol- and thioether-containing amino acids: Cystathionine and homocysteine families
Longobardo, Luigi,Cecere, Nunzia,DellaGreca, Marina,De Paola, Ivan
, p. 443 - 448 (2013/07/27)
Natural l-homocysteine and l,l-cystathionine, along with a series of unnatural analogues, have been prepared from l-aspartic and l-glutamic acid. Manipulation of the protected derivatives provided ω-iodoamino acids, which were used in thioalkylation react

Compounds of formula Ia or Ib in free or salt form, wherein Ar, X1, X2, m, R1, Q, Y, R2 and R3 have the meanings as indicated in the specification, are useful for treating conditions that are mediated by CCR-3, for example an inflammatory or allergic cond
Synthesis of enantiopure N-and C-protected homo-β-amino acids by direct homologation of α-amino acids
Caputo, Romualdo,Cassano, Ersilia,Longobardo, Luigi,Palumbo, Giovanni
, p. 12337 - 12350 (2007/10/02)
Enantiopure N-and/or C-protected homo-β-amino acids are prepared readily and in good yields from N-protected α-amino acids with the same side chain, via reduction of the carboxyl function and conversion of the resulting N-protected β-amino alcohol into the corresponding β-amino iodide and then β-amino cyanide. The key step of this strategy is represented by the synthesis of the enantiopure N-protected β-amino iodides 2 and 3 that are smoothly obtained from the parent amino alcohols 1 by polymer bound triarylphosphine-I2 complex in anhydrous dichloromethane.
