Abstract

Calonyctin A. extracted from Calonycfion aculeatum L. House (moonlight flower), exhibits a strongly promoting effect on the growth and yield of various crops like peanuts, beans, and wheat.", Calonyctin A consists of a mixture of the homologous 22-membered macrocycles 1 and I'(Scheme I), which are assembled from the tetrasaccharide D-Qui/?(1-3)[~-Rhact (1-2)]- ~-Qui/?(1-2)~-Qui and the aglycons 3-hydroxy-2-methylbutyric acid (nilic acid, 3) and 1 I- ...
