57491-33-5 Usage

Uses

(11E)-11-Hexadecenal is a monounsaturated 16 carbon aldehyde found in pheromones of insects.

Check Digit Verification of cas no

The CAS Registry Mumber 57491-33-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,4,9 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 57491-33:
(7*5)+(6*7)+(5*4)+(4*9)+(3*1)+(2*3)+(1*3)=145
145 % 10 = 5
So 57491-33-5 is a valid CAS Registry Number.

SYNTHESIS OF Z-OLEFIN-CONTAINING LEPIDOPTERAN INSECT PHEROMONES

-

Paragraph 0181; 0182, (2013/09/12)

The present invention is directed to methods of synthesizing insect pheromones, particularly lepidopteran insect pheromones, their precursors and derivatives from inexpensive, readily available starting materials using olefin metathesis catalysis.

SYNTHESIS OF TRANS-2,CIS-13- AND TRANS-3,CIS-13-OCTADECADIEN-1-OL ACETATES, COMPONENTS OF THE SEX PHEROMONE OF SYNANTHEDON TIPULIFORMIS (LEPIDOPTERA, SISIIDAE)

Sorochinskaya, A.M.,Kovalev, B.G.

, p. 621 - 624 (2007/10/02)

The Wittig-Horner reaction of ethoxycarbonylmethylenetriphenylphosphorane or ethyl diethylphosphonoacetic acid with cis-11-hexadecenal and the modified Knoevenagel reaction of this aldehyde with malonic acid gave the ethyl ester of trans-2,cis-13-octadecadienoic acid and trans,cis-13-octadecadienoic acid, which upon reduction and acetylation were converted into trans-2,cis-13- and trans-3-cis-13-octadecadien-1-yl acetates, which are components of the sex pheromone of Synanthedon tipuliformis (Lepidoptera, Sisiidae).

Pheromones via Organoboranes. 2. Vinylic Organoboranes. 8. Applications of the General Stereoselective Synthesis of (E)-Disubstituted Alkenes via Thexylchloroborane-Dimethyl Sulfide to the Synthesis of Pheromones Containing an (E)-Alkene Moiety

Brown, Herbert C.,Lee, Hsiupu D.,Kulkarni, Surendra U.

, p. 5282 - 5286 (2007/10/02)

Various (E)-pheromones of the general structure (E)-X-alken-1-yl acetates, (E)-X-alken-1-ols, and (E)-X-alken-1-als have been prepared via thexylchloroborane-dimethyl sulfide (ThxBHCl*SMe2).Hydroboration of acetate-functionalized alkenes with ThxBHCl*SMe2 gives cleanly the corresponding thexylalkylchloroboranes (ThxBRCl, B).Hydridation of B with potassium triisopropoxyhydride (KIPBH) at -78 deg C gives cleanly the corresponding thexylalkylboranes (ThxBRH, C).These are quenched immediately with 1-halo-1-alkynes to give B-(cis-1-halo-1-alkenyl)thexylalkylboranes (D).Treatment of D with sodium methoxide results in the displacement of bromine by the alkyl group on boron to produce B-(trans-1-alkyl-1-alkenyl)thexylborinates (E).Protonolysis of E with acetic acid provides (E)-X-alken-1-yl acetates in high yields and in >99percent isomeric purities.Treatment of (E)-X-alken-1-yl acetates with base affords the corresponding (E)-X-alken-1-ols.Oxidation of (E)-X-alken-1-ols with dimethyl sulfoxide activated by oxalyl chloride or the complex of dimethyl sulfide and chlorine produces (E)-X-alken-1-als quantitatively.By properly choosing the starting functionalized alkenes and 1-halo-1-alkynes, various (E)-pheromones can be prepared easily.The present procedure appears to be general.There does not appear to be any limitation on the length of the carbon chain or the position of the double bond in the target molecules.
