The introduction of sodium-liquid ammonia reduc-tion for the removal of benzyl-type and tosyl protecting groups was an essential milestone in thehistory of peptide chemistry about 50 years ago1-3 and significantly contributed to its speedy development resulting in the synthesis of carnosine2 in 1935, glutathione4 in 1936, oxytocin^ 9 in 1954, lysine-10-13 and arginine-va-sopressins14-17 in 1957. Over three decades this method was indispensable in the synthesis of peptides con-taining cysteine residues. Vincent du Vigneaud, the Nobel Prize Laureate of 1955 in chemistry, rendered an imperishable service in this work. Though the recognition of undesiredside reactions drew attention to the limits of itsapplications, the so-dium-liquid ammonia reduction is still a well-established protocol for the synthesis of analogues of oxy-tocin18 and the vasopressins, 19 and its advantages over acidolysis with hydrogen fluoride were recently em-phasized in the laststep of the synthesis of human/3-endorphin consisting of 31 amino acid residues. 20 Although a number of excellent textbooks21-28 deal from different points of view with some aspects of the application of sodium-liquid ammonia reduction in the field of general organic and peptide chemistry, no comprehensive review on this topic has been hitherto published. The scope of this review comprises the re-sults of sodium-liquid ammonia reduction in the re-moval of protecting groups in peptide chemistry with special emphasis on side reactions. Some data obtained in other fields, eg, carbohydrate, nucleotide, heterocyclic chemistry, etc., are included. Recent findings29-31 may give a new impetus to the application of sodium-
