Direct synthesis of sensitive selenocysteine peptides by the Ugi reaction

Ammonia and selenoaldehydes are both problematic components in Ugi reactions. Here we report the efficient direct multicomponent synthesis of sensitive selenocysteine peptides without the use of convertible (protected) primary amines, including suitable deprotection protocols for selenols.

LITHIUM DISELENIDE IN APROTIC MEDIUM - A CONVENIENT REAGENT FOR SYNTHESIS OF ORGANIC DISELENIDES

The reduction of selenium with lithium in THF in the presence of diphenylacetylene as a catalyst afforded lithium diselenide, which reacted with electrophiles giving alkyl or aryl diselenides 1 - 3 and selenides 4, as by-products.The useful method for preparation of diselenides based on this reaction was elaborated.
