913258-34-1 Usage

Uses

Used in Ophthalmology:
trans Latanoprost is used as an anti-glaucoma agent for reducing intraocular pressure in various types of glaucoma and ocular hypertension. It functions by increasing the outflow of aqueous humor, thus helping to manage and prevent further damage to the optic nerve.
Used in Urology:
trans Latanoprost is used as a PDE5 inhibitor for treating erectile dysfunction. It enhances the erectile response by increasing blood flow to the penis, allowing for a firmer and more sustained erection when sexually stimulated.

Check Digit Verification of cas no

The CAS Registry Mumber 913258-34-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,3,2,5 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 913258-34:
(8*9)+(7*1)+(6*3)+(5*2)+(4*5)+(3*8)+(2*3)+(1*4)=161
161 % 10 = 1
So 913258-34-1 is a valid CAS Registry Number.

Asymmetric Synthesis of Corey Lactone and Latanoprost

Hayashi, Yujiro,Umekubo, Nariyoshi

supporting information, p. 6221 - 6227 (2020/09/21)

Corey lactone was synthesized in a single pot within 152 minutes in a 50 % overall yield via pot and time economical manner. Latanoprost, an antiglaucoma blockbuster drug, was also synthesized via seven pot reaction with five purifications in a 25 % total yield. One of the key reactions is asymmetric domino Michael/Michael reaction, formal [3+2] cycloaddition reaction, of 3-(dimethylphenylsilyl)propenal and ethyl 4-oxo-2-pentenoate, catalyzed by diphenylprolinol silyl ether, which constructed the core substituted cyclopentanone derivative with nearly optically pure form.

Paragraph 0052; 0062-0064, (2020/10/21)

The present invention provides a novel latanoprost intermediate represented by chemical formula 1. In chemical formula 1, R is hydrogen or C_1-C_4 alkyl, P is hydrogen or a hydroxy protecting group, at least one P is a hydroxy protecting group. The hydroxy protecting group is represented by chemical formula 2. In chemical formula 2, R^1 is each independently -NO_2 or C_6-C_18 aryl, and R^1 is fused to a phenyl ring to form a C_10-C_18 aromatic ring.COPYRIGHT KIPO 2021

Access to a Key Building Block for the Prostaglandin Family via Stereocontrolled Organocatalytic Baeyer–Villiger Oxidation

Zhu, Kejie,Hu, Sha,Liu, Minjie,Peng, Haihui,Chen, Fen-Er

supporting information, p. 9923 - 9927 (2019/05/16)

A new protocol for the construction of a crucial bicyclic lactone of prostaglandins using a stereocontrolled organocatalytic Baeyer–Villiger (B-V) oxidation was developed. The key B-V oxidation of a racemic cyclobutanone derivative with aqueous hydrogen peroxide has enabled an early-stage construction of a bicyclic lactone skeleton in high enantiomeric excess (up to 95 %). The generated bicyclic lactone is fully primed with two desired stereocenters and enabled the synthesis of the entire family of prostaglandins according to Corey′s route. Furthermore, the reactivity and enantioselectivity of B-V oxidation of racemic bicyclic cyclobutanones were evaluated and 90–99 % ee was obtained, representing one of the most efficient routes to chiral lactones. This study further facilitates the synthesis of prostaglandins and chiral lactone-containing natural products to promote drug discovery.

An improved synthesis of latanoprost involving effective control on 15(S) diastereomer

Sasane, Sachin A.,Bhise, Nandu B.,Singh, Girij P.,Joseph, Alex,Shenoy, Gautham G.

, p. 2350 - 2356 (2019/07/31)

An improved process for the synthesis of latanoprost having excellent optical purity (de 99.9%, [α]D20 = +35.37° (c = 0.90, acetonitrile)) without use of preparative HPLC is described. This process involves effective purification of hydroxyl intermediate (5A) through solvent crystallization followed by inhibition of inversion of the chiral center at C-15 position. This was possible due to judicious use of diol intermediate (6) for double bond reduction prior to hydroxyl protection.

Enantio- and Diastereoselective Synthesis of Latanoprost using an Organocatalyst

Kawauchi, Genki,Umemiya, Shigenobu,Taniguchi, Tohru,Monde, Kenji,Hayashi, Yujiro

, p. 8409 - 8414 (2018/05/30)

An enantioselective total synthesis of latanoprost was achieved. Its chiral cyclopentane core structure was constructed through an organocatalyst-mediated [3+2]-cycloaddition reaction, and chirality in the ω-side chain was generated by prolinate-anion-mediated α-aminoxylation of an aldehyde. Highly diastereoselective domino acetalization and an oxy-Michael reaction were key steps for the generation of C9 chirality.

Synthesis of prostaglandin analogues, latanoprost and bimatoprost, using organocatalysis via a key bicyclic enal intermediate

Pr??vost, S??bastien,Thai, Karen,Sch??tzenmeister, Nina,Coulthard, Graeme,Erb, William,Aggarwal, Varinder K.

supporting information, p. 504 - 507 (2015/03/05)

Two antiglaucoma drugs, bimatoprost and latanoprost, which are analogues of the prostaglandin, PGF2?±, have been synthesized in just 7 and 8 steps, respectively. The syntheses employ an organocatalytic aldol reaction that converts succinaldehyde into a key bicyclic enal intermediate, which is primed for attachment of the required lower and upper side chains. By utilizing the crystalline lactone, the drug molecules were prepared in >99% ee.
