Enantioselective synthesis of α-ionone derivatives using an anti SN2′ substitution of functionalized zinc organometallics

(Equation Presented) The allylic substitution of sterically hindered (2-iodocycloalkyl)phosphates proceeds with complete anti SN2′ stereoselectivity with mixed diorganozincs of the type RZnCH 2SiMe3 in the presence of CuCN·2LiCI. Only the group R of the copper-zinc reagent is transferred in the allylic substitution. This method was used to prepare odoriferous substances such as (R)-α-ionone in 97% ee and (R)-dihydro-α-ionone in 98% ee.

Pheromone Synthesis, CXLVII. Synthesis of (1R,3S,6R,9S,10S)-9,10-Epoxytetrahydroedulan, the Main Component of the Hairpencil Secretion of Male Danaid Butterfly Eupoloea klugii

The natural and (+)-enantiomer of 9,10-epoxytetrahydroedulan decane>, the main component of the hairpencil secretion of Euploea klugii, was synthesized via (-)-dihydroedulan II (2) by starting from (S)-2,4,4-trimethyl-2-cyclohexen-1-ol (D).
