75445-60-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 75445-60-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,4,4 and 5 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 75445-60:
142 % 10 = 2
So 75445-60-2 is a valid CAS Registry Number.

A regioselective synthesis of 7-methyl juglone and its derivatives

Cui, Jiahua,Li, Shaoshun,Jia, Jinping

, p. 18 - 25 (2020/05/14)

7-Methyl juglone as a naturally occurring naphthoquinone showed striking antibacterial, antifungal, antivirus and anticancer activity. Its derivatives had also been characterized as key intermediates in the preparation of natural naphthoquinones and anthraquinones. Herein, we reported a regioselective synthesis of 7-methyl juglone via the construction of fused polycyclic systems. The key steps of the strategy involved Stobbe condensation of 2,5-dimethoxy benzaldehyde with diethyl succinate, intramolecular cyclization, reduction, acid-facilitated debenzylation and further cerium(IV) ammonium nitrate-mediated oxidation. Compared with the reported methods employing Birch conditions in liquid ammonia or Friedel-Crafts cycloacylation with melting heat of aluminum salts, the reaction conditions in the new synthetic route were milder and suitable for large scale preparations. In addition, all of the starting materials in the synthesis were readily available. It has great implications for the design and synthesis of structurally asymmetric naphthoquinones derivatives.

Total synthesis of isokidamycin

O'Keefe, B. Michael,Mans, Douglas M.,Kaelin Jr., David E.,Martin, Stephen F.

scheme or table, p. 15528 - 15530 (2011/01/12)

The synthesis of isokidamycin, which represents the first total synthesis of a bis-C-aryl glycoside natural product in the pluramycin family, has been completed. The synthesis features the use of a silicon tether as a disposable regiocontrol element in an intramolecular Diels-Alder reaction between a substituted naphthyne and a glycosyl furan and a subsequent O→C-glycoside rearrangement.
