Abstract A simple protocol for the preparation of N-protected amino alkyl thiols is reported that employs a reaction of sodium trithiocarbonate (Na2CS3) with N-protected amino alkyl iodides. Na2CS3 is easy to prepare and the protocol circumvents the use of strong bases and multiple steps. All the thiol compounds made were obtained as enantiopure samples and were characterized employing NMR and mass

been presented for the synthesis of Nβ-protected amino diselenides from the corresponding amino alkyliodidesusing in situ generated NaBH2Se3 as an efficient selenating reagent. All the diselenides are obtained in good yields under very mild conditions, short duration times and the protocol is free from racemization. The methodology has been effectively extended to the synthesis of N-protected L-selenocystine

The synthesis of a new class of amino phosphinodiselenoic acidester and β-amino diselenides is conducted by employing a reaction between Nβ-protected aminoalkyl iodide and phosphorus pentaselenide (P2Se5) has been described. In the presence of protic solvents, amino phosphinodiselenoic acidesters were found to be the major products, whereas β-amino diselenides were formed exclusively when the reaction

An efficient one-pot synthesis of Nα-protected S-linked 1,3,5-triazine tethered peptidomimetics is described. The protocol involves a three-component condensation reaction employing Nα-protected amino alkyl isothiouronium salt, formaldehyde and aminoacidester or aryl amine as reactants. Various aryl amines with substitutions and aminoacids with simple as well as bifunctional side chains were employed
