41096-47-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 41096-47-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,0,9 and 6 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 41096-47:
(7*4)+(6*1)+(5*0)+(4*9)+(3*6)+(2*4)+(1*7)=103
103 % 10 = 3
So 41096-47-3 is a valid CAS Registry Number.

A juvenile hormone analogs of the preparation method

-

Paragraph 0047; 0064-0065, (2017/05/10)

The invention relates to the field of insecticides, and particularly relates to a preparation method of a juvenile hormone analogue (which comprises S-methoprene and S-hydroprene). The preparation method of the juvenile hormone analogues comprises the following steps of: A. adding (2E, 4E)-11-R-3,7,11-trimethyl-2,4-dodecadienoic acid (R is hydrogen or methoxyl) serving as raw material, an organic alkali catalyst and an organic solvent to a reaction vessel, and starting stirring; B. dropwise adding an organic solvent (the same as the organic solvent in the step A) solution of pyrocarbonate; C. after the addition is completed, reacting at 0-30 DEG C for 0-3 hours; D. adding water to stop reaction, and splitting phases of reaction liquid to obtain an organic phase; E. carrying out reduced pressure concentration and distillation to obtain a product, wherein the steps can also be carried out under the condition that the addition sequences of the pyrocarbonate and an organic strongly-alkaline catalyst are exchanged. The preparation method disclosed by the invention has the advantages of mild reaction condition, high product purity, high yield, environment-friendly and safe route and good industrial prospect.

Preparation of alkyl 3-methylalka-2,4-dienoates from γ,δ-unsaturated β-keto esters via the corresponding conjugated unsaturated 3-enol phosphates

Moorhoff, Cornelis M.,Schneider, David F.

, p. 3279 - 3290 (2007/10/03)

Methylation of α,β,γ,δ-unsaturated-β-substituted enol phosphates with lithium dimethyl cuprate gave a mixture of (2E,4E)- and (2Z,4E) alkyl 3- methylalka-2,4-dienoates and unsubstituted alkyl alka-2,4-dienoates. An improved synthesis is described for ethyl β-safranate and the insect growth regulator hydroprene.

Synthesis of S-(+)-hydroprene

Odinokov, V. N.,Ishmuratov, G. Yu.,Kharisov, R. Ya.,Serebryakov, E. P.,Tolstikov, G. A.

, p. 100 - 101 (2007/10/02)

A novel path to S-(+)-hydroprene (1) starting from the technical grade S-(+)-dihydromyrcene (2, e.e. > 50percent) is proposed.The latter was selectively transformed into S-3,7-dimethyloctanal (5) in three steps including hydroalumination.The reactions of 5 with allyl- or methallylmagnesium chloride followed, respectively, either by oxygenation in the presence of PdCl2/CuCl or by ozonolysis, afford S,E-6,10-dimethyl-3-undecen-2-one (7) which was treated with ethoxyethynylmagnesium bromide to give the title juvenile hormone analogue in ca. 23percent overall yield.
