Synthesis and Biological Activity of Some Juvenile Hormone Analogs Lacking the Alkyl Substituents at C-7 or Both at C-3 and at C-7

Abstract

Two groups of juvenile hormone analogs were synthesized. One lacks the alkyl substituent at C-7. The other possesses the alkyl substituents neither at C-3 nor at C-7. These analogs were almost inactive on Bombyx mori L. Some of them with the alkyl substituent at C-3, however, were active on Tenebrio molitor L. This indicates the very narrow sensitivity of Bombyx mori L. to juvenile hormone analogs.
