4895-08-3

(1R,5R)-2-Methyl-5-(1-methylethenyl)-2-cyclohexen-1-methanol, also known as α-Terpineol, is a naturally occurring organic compound that belongs to the monoterpene alcohol class. It is a colorless to pale yellow liquid with a strong, pleasant odor, reminiscent of lilacs or pine needles. This chiral molecule is characterized by its asymmetric carbon atoms at positions 1 and 5, which give it a specific three-dimensional structure. α-Terpineol is widely found in various essential oils, such as those from citrus fruits, pine, and lavender, and is used in the fragrance and flavor industries due to its fresh, floral scent. It also has applications in the pharmaceutical and cosmetic industries, and is known for its antimicrobial properties.

4895-08-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4895-08-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,9 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4895-08:
(6*4)+(5*8)+(4*9)+(3*5)+(2*0)+(1*8)=123
123 % 10 = 3
So 4895-08-3 is a valid CAS Registry Number.

AN IMPROVED SYNTHESIS OF 1α,25-DIHYDROXYVITAMIN D A SYNTHONS

Castedo, L.,Mascarenas, J. L.,Mourino, A.

, p. 2099 - 2102 (1987)

A new improved preparation of key intermediate (9b, 11) for the synthesis of 1α,25-dihydroxyvitamin D is described.

Palladium-catalysed coupling of vinyl triflates with enynes and its application to the synthesis of 1α,25-dihydroxyvitamin D3

Mascarenas,Sarandeses,Castedo,Mourino

, p. 3485 - 3498 (2007/10/02)

We describe a general approach, based on the palladium-catalysed coupling of enynes with vinyl triflates, for the construction of dienynes related to vitamin D metabolites and analogues. As an application of this method, an efficient convergent synthesis of 1α,25-dihydroxyvitamin D3 starting from the Inhoffen-Lythgoe diol (6a) and natural carvones has been carried out (11 steps, 28% overall yield from 6a). This strategy allows labelling of the side chain in the final steps of the synthesis.
