Absolute configuration of the C18 juvenile hormone: application of a new circular dichroism method using tris(dipivaloylmethanato)praseodymium

Abstract

The absolute configuration of the C₁₈ juvenile hormone has been established as being (10R : 11S)-(I); this is based on clarification of the mode of epoxide cleavage, and a determination of the chirality of the resultant α-glycol by a new c.d. method employing Pr(dpm)₃.
