Check Digit Verification of cas no

The CAS Registry Mumber 88234-09-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,2,3 and 4 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 88234-09:
(7*8)+(6*8)+(5*2)+(4*3)+(3*4)+(2*0)+(1*9)=147
147 % 10 = 7
So 88234-09-7 is a valid CAS Registry Number.

Efficient synthesis of functionalized olefins by Wittig reaction using Amberlite resin as a mild base

Valkute, Tushar R.,Aratikatla, Eswar K.,Bhattacharya, Asish K.

, p. 581 - 589 (2017/03/15)

A convenient procedure for the synthesis of olefins by the reaction of stabilized, semistabilized, and nonstabilized phosphorous ylides with various aldehydes or ketone using Amberlite resin as a mild base is described. Our developed method offers facile and racemization-free synthesis of α,β-unsaturated amino esters and chiral allylic amine. The developed methodology offers mild reaction conditions, high efficiency, and facile isolation of the final products, a practical alternative to known procedures.

One-Step Synthesis of Substituted Benzofurans from ortho- Alkenylphenols via Palladium-Catalyzed C=H Functionalization

Yang, Dejun,Zhu, Yifei,Yang, Na,Jiang, Qiangqiang,Liu, Renhua

supporting information, p. 1731 - 1735 (2016/06/09)

A dehydrogenative oxygenation of C(sp2)=H bonds with intramolecular phenolic hydroxy groups has been developed, which provides a straightforward and concise access to structurally diversely benzofurans from ortho-alkenylphenols. The reaction is catalyzed by palladium on carbon (Pd/C) without any oxidants and sacrificing hydrogen acceptors.

A practicable environmentally benign one-pot synthesis of 2-arylbenzofurans at room temperature

Liao, Lian-Yan,Shen, Gang,Zhang, Xue,Duan, Xin-Fang

experimental part, p. 695 - 701 (2012/04/23)

An environmentallyfriendly one-pot synthesis of 2-arylbenzofurans under ambient temperature has been developed. It features an ortho-hydroxyl group assisted Wittig reaction of substituted salicylaldehyde followed by an in situ oxidative cyclization. Its advantages include readily available and non-hazardous materials, benign reaction conditions (room temperature, green solvent and one-pot manner), easy work-up and high overall yields. Utilizing this methodology, various 2-aryl-benzofurans including four natural products have been synthesized. The Royal Society of Chemistry 2012.

Direct olefination of benzaldehydes into hydroxy functionalized oligo (p-phenylenevinylene)s via Pd-catalyzed heterodomino Knoevenagel- decarboxylation-Heck sequence and its application for fluoride sensing π-conjugated units

Sharma, Abhishek,Sharma, Naina,Kumar, Rakesh,Shard, Amit,Sinha, Arun K.

supporting information; experimental part, p. 3283 - 3285 (2010/07/13)

A new approach for one step olefination of benzaldehydes into hydroxy functionalized OPVs is achieved through the first domino Knoevenagel- decarboxylation-Heck sequence using a single catalyst system. The methodology also led to new oxygen based OPV scaffolds capable of selective and visible fluoride recognition in organic or aqueous medium.

Remarkable synergism in methylimidazole-promoted decarboxylation of substituted cinnamic acid derivatives in basic water medium under microwave irradiation: a clean synthesis of hydroxylated (E)-stilbenes

Kumar, Vinod,Sharma, Abhishek,Sharma, Anuj,Sinha, Arun K.

, p. 7640 - 7646 (2008/02/09)

A metal-free protocol for decarboxylation of substituted α-phenylcinnamic acid derivatives in aqueous media is developed, wherein a remarkable synergism between methylimidazole and aq NaHCO3 in polyethylene glycol under microwave furnished the corresponding para/ortho hydroxylated (E)-stilbenes in a mild and efficient manner. The critical role of water in facilitating the decarboxylation imparts an interesting facet to the synthetic utility of water mediated organic transformations. The developed protocol provides a clean alternative to the hitherto indispensable multistep approaches involving toxic quinoline and a copper salt combination as the common decarboxylating agent.

A facile two-step synthesis of 2-arylbenzofurans based on the selective cross McMurry couplings

Duan, Xin-Fang,Zeng, Jing,Zhang, Zhan-Bin,Zi, Guo-Fu

, p. 10283 - 10286 (2008/04/05)

(Chemical Equation Presented) A novel two-step synthesis of 2-arylbenzofurans has been developed. It involves a selective cross McMurry coupling of a salicylaldehyde or substituted salicylaldehyde with an aromatic aldehyde and a sequential oxidative cyclization of the resulting ortho-vinylphenols. Utilizing this synthetic protocol, a variety of 2-arylbenzofurans including cicerfuran (5) have been efficiently synthesized.

An unusual, mild and convenient one-pot two-step access to (E)-stilbenes from hydroxy-substituted benzaldehydes and phenylacetic acids under microwave activation: a new facet of the classical Perkin reaction

Sinha, Arun K.,Kumar, Vinod,Sharma, Abhishek,Sharma, Anuj,Kumar, Rakesh

, p. 11070 - 11077 (2008/02/12)

A mild and convenient one-pot two-step synthesis of hydroxystilbenes with trans selectivity has been developed through a modified Perkin reaction between benzaldehydes and phenylacetic acids bearing 4- or 2-hydroxy substitution at the aromatic ring, in the presence of piperidine-methylimidazole and polyethylene glycol under microwave irradiation. The observation of a simultaneous condensation-decarboxylation leading to the unusual formation of hydroxystilbenes in lieu of α-phenylcinnamic acid reveals an interesting facet to the classical Perkin reaction. The developed protocol provides a green alternative to the prevalent methods employing a toxic decarboxylating agent in the form of quinoline/Cu salt, and the requirement for harsh protection-deprotection steps for the synthesis of hydroxylated stilbenes.

The invention entitled "A Microwave Induced One Pot Process for The Preparation of Arylethenes" provides a method for the preparation of commercially important 2- or 4-hydroxy substituted arylethenes like styrenes or stilbenes in one pot utilizing cheaper substrates in the form of 2- or 4-hydroxy substituted cinnamic acids and their derivatives as well as reagents in the form of base such as sodium hydroxide, potassium hydroxide, lithium hydroxide, sodium bicarbonate, sodium carbonate, potassium bicarbonate, potassium carbonate, ammonium acetate, imidazole, methylimidazole and the combination thereof, with or without solvent such as dimethylformamide, dimethylsulfoxide, ethylene glycol, diethylene glycol, acetonitrile, acetone, methyl imidazoles, ionic liquid, water and the like. The reaction time vary from 1 min-12 hrs and yield of the products from 49-76% depending upon the base, acid, substrate source of heating monomode or multimode microwave or conventional. It is important to mention that the presence of 2- or 4-hydroxy substitution at phenyl ring of cinnamic acids and their derivatives is essential requirements towards formation of corresponding arylethenes in one step.
