Stereoselective total syntheses of insect juvenile hormones JH 0 and JH i

Total syntheses of juvenile hormones JH 0 and JH I have been achieved by a new iterative enol tosylate homologation strategy. Georg Thieme Verlag Stuttgart · New York.

New enantioselective synthesis of (10R, 11S)-(+)-juvenile hormones I and II

The (10R,11S)-(+)-juvenile hormones I (1) and II (2) were synthesized by Sharpless asymmetric dihydroxylations of methyl (2E, 6E, 10E)-7-ethyl-3,11-dimethyl-2,6,10-tridecatrienoate (4) and methyl (2E,6E,10E)-3,7,11-trimethyl-2,6,10-tridecatrienoate (5), respectively, as the key steps.

SYNTHESIS OF ENANTIOMERICALLY PURE (10R, 11S)-(+)-JUVENILE HORMONES I AND II

Enantiomerically pure (+)-juvenile hormone I18JH=JH I> and (+)-juvenile hormone II 17 JH=JH II> were synthesized employing the enantioselective reduction of 2-ethyl-2-methyl-1,3-cyclohexanedione by a yeast (Pichia terricola KI0117) as the key step.
