1623154-48-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1623154-48-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,3,1,5 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1623154-48:
(9*1)+(8*6)+(7*2)+(6*3)+(5*1)+(4*5)+(3*4)+(2*4)+(1*8)=142
142 % 10 = 2
So 1623154-48-2 is a valid CAS Registry Number.

Anchored sulfonic acid on silica-layered NiFe2O4: A magnetically reusable nanocatalyst for Hantzsch synthesis of 1,4-dihydropyridines

Zeynizadeh, Behzad,Rahmani, Soleiman,Eghbali, Elham

, p. 57 - 66 (2019)

In this study, the immobilization of sulfonic acid on silica-layered nickel ferrite, NiFe2O4@SiO2@SO3H, was investigated. The sulfonated Ni-nanocatalyst was then characterized using FT-IR, SEM, EDX, XRD and VSM analyses. Catalytic activity of the Ni-nanocomposite was also studied towards Hantzsch synthesis of 1,4-dihydropyridines via one-pot condensation reaction of 1,3-diketones (ethyl acetoacetate or 4-hydroxycoumarin), aromatic aldehydes and aqueous ammonia in H2O (70 °C)as a green solvent. All reactions were carried out within 10–100 min to afford the products in high to excellent yields. The green aspect of this synthetic protocol was more studied by examining the reusability of NiFe2O4@SiO2@SO3H MNPs for seven consecutive cycles without the significant loss of catalytic activity. The current method represents remarkable advantages in terms of mild reaction conditions, using H2O as an environmental-friendly solvent, stability and easy separation of the magnetic nanocatalyst, high yield of products, wide tolerance of starting materials and the perfect reusability of the applied Ni-nanocatalyst.

Guanidinium-based sulfonic acid: an efficient Br?nsted acid organocatalyst for the synthesis of fused polycyclic dihydropyridines in water

Shaabani, Ahmad,Shaabani, Shabnam,Seyyedhamzeh, Mozhdeh,Sangachin, Mona Hamidzad,Hajishaabanha, Fatemeh

, p. 7247 - 7256 (2016)

Abstract: An efficient and eco-friendly protocol for the synthesis of polycyclic dihydropyridine scaffolds has been developed from readily accessible 4-hydroxycoumarin, aldehydes, and ammonium acetate in the presence of guanidinium-based sulfonic acid as a Br?nsted acid organocatalyst. This method provides several advantages, such as simple work-up procedure, environmentally benign, recyclable catalyst, and high yields. In addition, water was chosen as a green solvent.

Background: 1,4 Dihydropyridines (1,4 DHPs), chromeno[4,3-b] quinolines and pyrimido [4,5-b]quinolines are biologically and pharmaceutically important heterocycles. They are also present in many natural products. Many methods have been applied for their s

An efficient 'on-water' synthesis of 1,4-dihydropyridines using Fe3O4@SiO2nanoparticles as a reusable catalyst

Dam, Binoyargha,Nandi, Sibaji,Pal, Amarta Kumar

supporting information, p. 5236 - 5240 (2015/01/09)

An 'on-water', efficient, high yielding, expeditious method has been developed for the synthesis of 1,4-dihydropyridine (1,4-DHP) derivatives via an one-pot multi-component condensation of dimedone or 4-hydroxycoumarine, aldehydes, and ammonium acetate using Fe3O4@SiO2nanoparticles as a recyclable heterogeneous catalyst. This method takes advantage of the fact that water, a green solvent is used in combination with Fe3O4@SiO2nanoparticles as catalyst which can be easily recovered magnetically and reused for further runs.

An aqua mediated facile synthesis of conformationally restricted polycyclic dihydropyridines

Kidwai, Mazaahir,Kukreja, Shuchi,Rastogi, Shweta,Singhal, Kavita,Mishra, Neeraj Kumar

, p. 605 - 609 (2014/06/23)

An economically and environmentally benign synthesis of 4-substituted-dihydropyridines (DHPs) is described from readily accessible 4-hydroxy coumarin with aldehydes and ammonium nitrate that are accelerated by exposure to microwaves. The reaction completes within a few minutes with good yields. The mechanistic detail of methodology includes Michael type addition of β-aminobenzopyran-2-one across the double bond of arylidine formed by the condensation of 4-hydroxycoumarin with aldehyde in aq. medium. The main advantages of the protocol reported here is absence of use of strong acid or expensive catalyst, good yields, easy work-up and almost no effluent generation.
