7488-49-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7488-49-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,8 and 8 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7488-49:
(6*7)+(5*4)+(4*8)+(3*8)+(2*4)+(1*9)=135
135 % 10 = 5
So 7488-49-5 is a valid CAS Registry Number.

-

, (2020/07/15)

The invention discloses a pentazocine prodrug shown as a formula (I), a preparation method thereof and medical application of a pharmaceutical preparation containing the pentazocine prodrug, wherein Ris hydrogen or deuterium. The water solubility of the prodrug compound is improved by 20 times or above at room temperature, the prodrug compound is chemically stable, the onset time is delayed, thedrug effect is prolonged, meanwhile, the same parent drug blood concentration is generated at a low dosage, and the prodrug compound has a wide clinical application prospect.

Enantiocontrolled synthesis of (-)-9-epi-pentazocine and (-)-aphanorphine

Yang, Xiaobao,Zhai, Hongbin,Li, Zhong

supporting information; experimental part, p. 2457 - 2460 (2009/05/26)

(Chemical Equation Presented) We have developed novel asymmetric routes to (-)-9-epi-pentazocine and (-)-aphanorphine from a D-tyrosine derivative. The tricyclic frameworks of (-)-9-epi-pentazocine and (-)-aphanorphine were assembled stereoselectively via intramolecular Friedel-Crafts reaction of the corresponding bicyclic precursors, generated with titanium-promoted enyne cyclization and indium-initiated atom-transfer radical cyclization, respectively.

Migratory hydroamination: A facile enantioselective synthesis of benzomorphans

Trost, Barry M.,Tang, Weiping

, p. 8744 - 8745 (2007/10/03)

We describe a highly efficient, general strategy for the enantioselective synthesis of benzomorphans (45-46% overall yield from commercially available material). The new synthesis demonstrates the effectiveness of an unprecedented diastereoselective cycloisomerization via migratory hydroamination and the power of palladium-catalyzed asymmetric allylic alkylation (AAA) of simple ketone enolates in the context of complex synthesis. The strategy outlined here for the enantioselective synthesis of three contiguous stereogenic centers and the novel cycloisomerization should have many applications in alkaloid synthesis. Copyright
