331677-32-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 331677-32-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,1,6,7 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 331677-32:
(8*3)+(7*3)+(6*1)+(5*6)+(4*7)+(3*7)+(2*3)+(1*2)=138
138 % 10 = 8
So 331677-32-8 is a valid CAS Registry Number.

Functionalization of Piperidine Derivatives for the Site-Selective and Stereoselective Synthesis of Positional Analogues of Methylphenidate

Babl, Tobias,Davies, Huw M. L.,Liu, Wenbin,R?ther, Alexander,Reiser, Oliver

supporting information, (2020/03/23)

Rhodium-catalyzed C?H insertions and cyclopropanations of donor/acceptor carbenes have been used for the synthesis of positional analogues of methylphenidate. The site selectivity is controlled by the catalyst and the amine protecting group. C?H functionalization of N-Boc-piperidine using Rh2(R-TCPTAD)4, or N-brosyl-piperidine using Rh2(R-TPPTTL)4 generated 2-substitited analogues. In contrast, when N-α-oxoarylacetyl-piperidines were used in combination with Rh2(S-2-Cl-5-BrTPCP)4, the C?H functionalization produced 4-susbstiuted analogues. Finally, the 3-substituted analogues were prepared indirectly by cyclopropanation of N-Boc-tetrahydropyridine followed by reductive regio- and stereoselective ring-opening of the cyclopropanes.

One-Pot Bimetallic Pd/Cu-Catalyzed Synthesis of Sulfonamides from Boronic Acids, DABSO and O-Benzoyl Hydroxylamines

Zhu, Haibo,Shen, Yajing,Deng, Qinyue,Huang, Changyu,Tu, Tao

, p. 706 - 712 (2017/03/22)

A practical and straightforward bimetallic Pd/Cu catalytic system has been developed. This system affords various sulfonamides in one pot from easy-to-handle and readily available boronic acids, sulfur dioxide surrogate DABSO and O-benzoyl hydroxylamines in high yields. Without additional ligands, the newly developed catalytic system revealed a broad substrate scope for both partners and tolerated a wide array of functional groups even at low catalyst loadings. Furthermore, based on control experiments, a plausible mechanism has been proposed, in which sodium sulfinate has been isolated and identified as the crucial intermediate for this transformation.

Copper(i)-catalyzed sulfonylative Suzuki-Miyaura cross-coupling

Chen, Yiding,Willis, Michael C.

, p. 3249 - 3253 (2017/04/04)

Using a simple copper(i) catalyst has allowed a high yielding sulfonylative-Suzuki-Miyaura cross-coupling reaction to be developed. The process provides a single step route to diaryl sulfones from the direct combination of aryl boronic acids, sulfur dioxide and aryl iodides, and represents the first sulfonylative variant of a classic cross-coupling reaction. Sulfur dioxide is delivered from the surrogate reagent, DABSO. Variation of the reaction conditions allowed interruption of the sulfonylative-Suzuki coupling, resulting in the formation of a presumed Cu-sulfinate intermediate. These sulfinates could be trapped as their sodium salts and treated with electrophiles to allow access to arylalkyl sulfones, β-hydroxyl sulfones, sulfonamides and sulfonyl fluorides.

Iron-catalyzed synthesis of arylsulfinates through radical coupling reaction

Zhang, Weixi,Luo, Meiming

, p. 2980 - 2983 (2016/02/19)

A novel strategy for installation of a sulfonyl fragment into arenes has been accomplished via an iron-catalyzed radical coupling reaction. Arene radicals derived from diaryliodoniums via single electron transfer reaction combine with sulfoxylate anion radicals readily generated from commercially available rongalite (HOCH2SO2Na·2H2O) to afford arylsulfinates efficiently at room temperature. In this protocol, a broad range of functional groups are tolerated to give products in good yields.
