    (Addis Ababa Universty, 1982-06) Alemayehu Gizachew; Dagne Ermias (PhD)
    As part of our attempts to synthesize Kosotoxin (1) simple synthetic procedures for the synthesis of related compounds !, ~,. 52,ยท shown below have been developed. Furthermore D and F which are key intermediates for the synthesis of Kosotoxin analogues,. and! and Q which are supposed to be kosotoxin analogues have also been synthesized. In addition the chemistry of unsymmetrical condensa~ tion of acylated poly hydroxy compounds has been studied
