General Description
2(3H)-Furanone, dihydro-3-methyl-, (S)- is a chemical compound that is commonly used as a food additive to enhance the flavor of a variety of food products. It has a sweet, caramel-like odor and is often added to baked goods, beverages, and dairy products to impart a pleasant, caramel-like flavor. The (S)-enantiomer of this compound is the natural form and is produced by certain microorganisms. It is considered safe for consumption in small amounts, but there may be potential health risks associated with high levels of exposure. Overall, 2(3H)-Furanone, dihydro-3-methyl-, (S)- is a commonly used flavoring agent that can contribute to the overall sensory experience of various food products.
Check Digit Verification of cas no
The CAS Registry Mumber 65527-79-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,5,2 and 7 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 65527-79:
(7*6)+(6*5)+(5*5)+(4*2)+(3*7)+(2*7)+(1*9)=149
149 % 10 = 9
So 65527-79-9 is a valid CAS Registry Number.

Asymmetric hydroformylation of allylic alcohols catalyzed by Rh(I)-(R,S)-BINAPHOS

Chiral lactones 4a-e were synthesized by the asymmetric hydroformylation of allylic alcohols 1a-e and 5 catalyzed by a rhodium(I) complex of a chiral phosphine-phosphite, (R,S)-BINAPHOS, followed by the silver(I) oxidation.
Asymmetric Synthesis of 2-Substituted Butyrolactones and Valerolactones
Meyers, A. I.,Yamamoto, Yukio,Mihelich, Edward D.,Bell, Richard A.

The use of chiral oxazolines 1, 2, 5, and 8 under asymmetrically induced alkylation conditions gave α-substituted oxazolines 3, 6, 9, and 13 which were hydrolyzed to α-substituted butyro- and valerolactones 4 and 11.Either enantiomer of the lactones could be prepared in predictable absolute configuration by reversing the order of alkyl group introduction.The lactones were prepared in 60-86 percent enantiomeric excess which was determined by either chemical correlation or high-pressure liquid chromatography of the diastereomers 10.
