STEREOSELECTIVE SYNTHESIS OF NATURAL (4S,6S,7S)-SERRICORNIN STARTING WITH (3S,4S)-4-HYDROXY-3-METHYL-1-HEXENE

(4S,6S,7S)-Serricornin has been synthesized in three steps starting with (3S,4S)-4-hydroxy-3-methyl-1-hexene.

Synthesis of (4R,6S,7R)-7-hydroxy-4,6-dimethyl-3-nonanone and (3R,5S,6R)-6-hydroxy-3,5-dimethyl-2-octanone

The synthesis of (4R,6S,7R)-7-hydroxy-4,6-dimethyl-3-nonanone and (3R,5S,6R)-6-hydroxy-3,5-dimethyl-2-octanone is described as their acetates using a desymmetrization strategy as well as an Evans syn aldol strategy.

Thiopyran route to polypropionates: An efficient synthesis of serricornin

The synthesis of serricornin [(4S,6S,7S)-7-hydroxy-4,6-dimethylnonan-3-one] , a sex pheromone produced by the female cigarette beetle (Lasioderma serricorne F.), in seven steps from readily available racemic 1,4-dioxa-8-thiaspiro-[4.5] decane-6-carboxaldehyde (6) is described. The key steps include enantioselective aldol reaction of 6 with tetrahydrothiopyran-4-one catalyzed by 5-[(2S)-pyrrolidine-2-yl]-1H-tetrazole to fabricate the tetrapropionate skeleton, stereoselective LisBu3BH reduction of the resulting aldol adduct, Barton-McCombie deoxygenation, and Raney nickel desulfurization.

Synthesis of a biologically active analog of the sex pheromone of cigarette beetle (Lasioderma serricorne)

A simple synthesis of a diastereomeric mixture of 7-hydroxy-4,6- dimethylnonan-3-ones was carried out. In the biological action, it is an analog of serricornin, the sex pheromone of the cigarette beetle (Lasioderma serricorne).

Synthesis of (4R,6S,7R)-7-hydroxy-4,6-dimethyl-3-nonanone and (3R,5S,6R)-6-hydroxy-3,5-dimethyl-2-octanone, the pheromone components of the bostrychid beetle, Dinoderus bifoveolatus

(4R,6S,7R)-7-Hydroxy-4,6-dimethyl-3-nonanone and (3R,5S,6R)-6-hydroxy-3,5- dimethyl-2-octanone, the pheromone components of the bostrychid beetle, Dinoderus bifoveolatus, as well as their (4R,6S,7S)-and (3R,5S,6S)-isomers were synthesized from (2R,4S,5R)- and (2R,4S,5S)2,4-dimethyl-5-heptanolide, respectively.

New synthesis of serricornin, the sex pheromone of the cigarette beetle (Lasioderma serricorne)

A new approach to the total synthesis of serricornin, the sex pheromone of the cigarette beetle, based on readily available (4S,5E)-4-methyhept-5-enenitrile was implemented.

New synthesis of serricornin, the female sex pheromone of the cigarette beetle

Serricornin [(4S,6S,7S)-7-hydroxy-4,6-dimethyl-3-nonanone], the female sex pheromone of Lasioderma serricorne, was synthesized by starting from (2S,4S)-2,4-dimethyl-1,5-pentanediol that had been obtained by lipase-catalyzed enantiomer separation of its racemate.

The baker's yeast reduction of the β-keto aldehydes in the presence of a sulfur compound

Improved enantio- and diastereoselectivity was achieved in the baker's yeast reduction of β-keto aldehyde derivatives using a sulfur compound as an additive. The resulting enantiomerically pure diol was transformed into serricornin, a sex pheromone of the cigarette beetle.

Enantioselective Synthesis of (-)-Serricornin, a Sex Pheromone of a Female Cigarette Beetle (Lasioderma serricorne F.)

(-)-Serricornin, a sex pheromone of a cigarette beetle (Lasioderma serricorne F.), has been synthesized highly stereoselectively starting from (Z)-4-benzyloxy-2-buten-1-ol by employing the Katsuki-Sharpless asymmetric epoxidation and two stereospecific me

AN EFFICIENT AND STEREOSELECTIVE TOTAL SYNTHESIS OF (+/-)-SERRICORNINE

An efficient and stereoselective total synthesis of (+/-)-serricornine (1) the sex pheromone produced by the female cigarette beetle Lasioderma serricorne F, is described. (3SR,5SR,6SR)-6-Ethyltetrahydro-3,5-dimethyl-2H-pyran-2-one (10) is prepared in 65percent yield through lactonization of a 1:1 mixture of C-2 epimrs of the corresponding esters.
