General Description

The chemical compound (4R,5S)-(2,2-dimethyl-5-vinyl-1,3-dioxolan-4-yl)methan-1-ol, also known as 4R,5S-dimethyl-5-vinyl-1,3-dioxolan-4-ol, is a chiral molecule with a dioxolane ring structure. It is often used as a building block in the synthesis of pharmaceuticals, agrochemicals, and other organic compounds. (4R,5S)-(2,2-dimethyl-5-vinyl-1,3-dioxolan-4-yl)methan-1-ol contains a hydroxyl group, making it a potential intermediate for the creation of various functionalized molecules. Its unique structure and reactivity make it a valuable component in organic chemistry and drug development.

Check Digit Verification of cas no

The CAS Registry Mumber 127758-25-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,7,5 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 127758-25:
(8*1)+(7*2)+(6*7)+(5*7)+(4*5)+(3*8)+(2*2)+(1*5)=152
152 % 10 = 2
So 127758-25-2 is a valid CAS Registry Number.

Highly active chiral ruthenium catalysts for asymmetric cross- and ring-opening cross-metathesis

Berlin, Jacob M.,Goldberg, Steven D.,Grubbs, Robert H.

, p. 7591 - 7595 (2006)

Metathesis takes sides: The scope of asymmetric metathesis has been expanded with the use of chiral ruthenium catalysts for asymmetric ring-opening cross-metathesis and for the first example of an asymmetric cross-metathesis (see scheme, TIPS = triisoprop

First asymmetric total synthesis of aspergillide D

Jena, Bighnanshu K.,Reddy, G. Sudhakar,Mohapatra, Debendra K.

supporting information, p. 1863 - 1871 (2017/03/09)

The first asymmetric total synthesis of a 16-membered macrolide, aspergillide D, is described. The chiral centers of the acid are derived from d-ribose and the alcohol subunit from 1,8-octane diol through Sharpless kinetic resolution, respectively. The other key reactions include Yamaguchi esterification, ring-closing metathesis reaction, and Shiina macrolactonization to construct the fully functionalized macrocycle.
