Safety Profile

A questionable carcinogen. A flammable liquid. When heated to decomposition it emits acrid smoke and irritating vapors.

Check Digit Verification of cas no

The CAS Registry Mumber 7448-86-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,4 and 8 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7448-86:
(6*7)+(5*4)+(4*4)+(3*8)+(2*8)+(1*6)=124
124 % 10 = 4
So 7448-86-4 is a valid CAS Registry Number.

Rational modification of Mannich base-type derivatives as novel antichagasic compounds: Synthesis, in vitro and in vivo evaluation

Paucar, Rocío,Martín-Escolano, Rubén,Moreno-Viguri, Elsa,Azqueta,Cirauqui,Marín, Clotilde,Sánchez-Moreno, Manuel,Pérez-Silanes, Silvia

, p. 3902 - 3917 (2019)

The current chemotherapy against Chagas disease is inadequate and insufficient. A series of ten Mannich base-type derivatives have been synthesized to evaluate their in vitro antichagasic activity. After a preliminary screening, compounds 7 and 9 were sub

Rongalite as C1 Synthon and Sulfone Source: A Practical Sulfonylmethylation Based on the Separate-Embedding Strategy

Chen, Xiang-Long,Wu, Chun-Yan,Ma, Jin-Tian,Zhuang, Shi-Yi,Yu, Zhi-Cheng,Wu, Yan-Dong,Wu, An-Xin

supporting information, p. 223 - 227 (2022/01/04)

Rongalite has been used in several challenging synthetic transformations with operationally simple and effective protocols. However, the employment of multiple characteristics of rongalite in synthetic chemistry is comparatively little known. Herein we report a separate-embedding type sulfonylmethylation of sulfoxonium ylides in which rongalite concurrently acted as a sulfone source, C1 synthon, radical initiator, and potential reducing reagent for the first time. Notably, this facile and easy-handling reaction does not require a catalyst or prefunctionalized sulfonylmethylation reagents.

Nickel-Catalyzed C(sp3)-H Functionalization of Benzyl Nitriles: Direct Michael Addition to Terminal Vinyl Ketones

Zhang, Ninghui,Zhang, Chunli,Hu, Xiaoping,Xie, Xin,Liu, Yuanhong

supporting information, p. 6004 - 6009 (2021/07/31)

An efficient nickel(0)-catalyzed addition of benzyl nitriles to terminal vinyl ketones via C(sp3)-H functionalization has been developed. The reaction provides a novel and efficient protocol for the synthesis of α-functionalized benzyl nitriles with a wide range of structural diversity under mild reaction conditions while obviating the use of a strong base. The work might be potentially useful toward the development of an enantioselective variant using chiral nitrogen ligands.

Enantioselective Copper-Catalyzed Electrophilic Sulfenylation of Cyclic Imino Esters

Chen, Zhiwei,Lin, Huaxin,Han, Jian,Fang, Dongmei,Wang, Min,Liao, Jian

supporting information, p. 9146 - 9150 (2021/11/30)

Herein we report an enantioselective sulfenylation of cyclic imino esters with the efficient and versatile sulfenylation reagent S-alkyl 4-methylbenzenesulfonothioates. By utilizing the Cu/tBu-Phosferrox catalytic system, we can assemble diverse S-alkyl groups into the cyclic imino esters under mild conditions in good yields and with excellent enantioselectivities. Remarkably, this method demonstrates a high tolerance of diverse functional groups and proves to be applicable in the late-stage functionalization of pharmaceuticals.
