502-70-5 Usage

Uses

Crocetindial is an antioxidant β-carotene (C184250) found in saffron. It is useful in ameliorating various diseases, including neurodegenerative disorders.

Check Digit Verification of cas no

The CAS Registry Mumber 502-70-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,0 and 2 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 502-70:
(5*5)+(4*0)+(3*2)+(2*7)+(1*0)=45
45 % 10 = 5
So 502-70-5 is a valid CAS Registry Number.

A Short and Efficient Synthesis of Crocetin-dimethylester and Crocetindial

Frederico, Daniel,Marcos Donate, Paulo,Gomes Constantino, Mauricio,Soares Bronze, Erika,Sairre, Mirela I.

, p. 9126 - 9128 (2003)

In this paper we describe an efficient six-step synthesis of crocetin-dimethylester that could be further reduced to a "four-step" synthesis through the use of in situ procedures. The simplicity of the whole process, the ready availability of starting materials, and the high overall yield render this strategy a very attractive synthesis of this very important compound, which is the key intermediate for the synthesis of several carotenoids and other polyene natural products.

Sulfone-mediated syntheses of crocetin derivatives: Regioselectivity of highly functionalized building blocks

Oh, Eun-Taek,Kim, Young-Hun,Jin, Jingquan,Su, Liang,Seo, Jung-Ah,Koo, Sangho

, p. 4712 - 4717 (2014/06/09)

New C5 sulfone building blocks containing a masked polar end group have been devised for the efficient synthesis of carotenoids with polar termini. Chemoselectivity or the regiochemical issue of the highly functionalized units has been carefully addressed depending on the soft or hard nature of electrophiles. These building blocks have been successfully applied to the syntheses of crocetin derivatives, crocetin dial and the novel crocetin dinitrile.

METHODS FOR SYNTHESIS OF CHIRAL INTERMEDIATES OF CAROTENOIDS, CAROTENOID ANALOGS, AND CAROTENOID DERIVATIVES
