(3R*,4R*)-4-hydroxy-3-methylhexene is a chiral organic compound characterized by its unique molecular structure. It features a hydroxyl group (-OH) at the 4th carbon position and a methyl group (-CH3) at the 3rd carbon position. The compound's chirality arises from the presence of two asymmetric carbon centers, which are the 3rd and 4th carbon atoms, denoted by the R* and R* configurations, respectively. This specific arrangement of functional groups and stereochemistry gives rise to distinct physical and chemical properties compared to its enantiomers and diastereomers. The compound's structure can be represented as a hexene chain with a hydroxyl group and a methyl group attached to specific carbons, which influences its reactivity and potential applications in various chemical and pharmaceutical processes.

1538-21-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1538-21-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,3 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1538-21:
(6*1)+(5*5)+(4*3)+(3*8)+(2*2)+(1*1)=72
72 % 10 = 2
So 1538-21-2 is a valid CAS Registry Number.

Allylstannation X. Stereochemical course of the Addition Reactions of (E/Z)-Bu3SnCH2CH=CHCH3 with Aldehydes in the Presence of Lewis Acids (Bu2SnCl2, BF3.Et2O, and TiCl4)

Boaretto, Andrea,Marton, Daniele,Tagliavini, Giuseppe,Ganis, Paolo

, p. 199 - 208 (2007/10/02)

Reactions between (E/Z)-Bu3SnCH2CH=CHCH3 and RCHO (R= CH3, C2H5, n-C3H7, n-C4H9, n-C5H11, (CH3)2CH, (CH3)3C, C6H5, CH2=CH, CH2=C(CH3), (E)-CH3CH=CH, (E)-C3H7CH=CH, (E)-C6H5CH=CH) have been carried out in the presence of Lewis acids such as Bu2SnCl2, BF3.Et2O, and TiCl4.The stereochemical course of the reactions to give homoallylic alcohols does not necessarily depend on the formation of intermediate Lewis acid-aldehyde complexes, but rather upon the formation of allylmetal compounds (e.g.Bu2ClSnCH2CH=CHCH3, Bu2ClSnCH(CH3)CH=CHCH2, Cl3TiCH2CH=CHCH3, etc.) which are the actual species which react with the carbonyl compounds.Bu3SnCH2CH=CHCH3 does not undergo the reaction.
