81734-85-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81734-85-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,7,3 and 4 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81734-85:
(7*8)+(6*1)+(5*7)+(4*3)+(3*4)+(2*8)+(1*5)=142
142 % 10 = 2
So 81734-85-2 is a valid CAS Registry Number.

A One-Pot Approach to 2,3-Diarylbenzo[ b]furans through N-Heterocyclic Carbene-Catalyzed 1,6-Conjugate Addition Followed by Acid Mediated Dehydrative Annulation

Singh, Gurdeep,Goswami, Prithwish,Sharma, Sonam,Anand, Ramasamy Vijaya

, p. 10546 - 10554 (2018)

A one-pot protocol for the synthesis of 2,3-diarylbenzo[b]furan derivatives through an N-heterocyclic carbene catalyzed 1,6-conjugate addition of aromatic aldehydes to 2-hydroxyphenyl-substituted para-quinone methides followed by acid-mediated dehydrative annulation has been developed. This protocol allowed us to access a wide range of 2,3-diarylbenzo[b]furan derivatives in moderate to good yields.

Synthesis of Functionalized Benzofurans from para-Quinone Methides via Phospha-1,6-Addition/ O-Acylation/Wittig Pathway

Liou, Yan-Cheng,Karanam, Praneeth,Jang, Yeong-Jiunn,Lin, Wenwei

supporting information, p. 8008 - 8012 (2019/10/16)

An efficient synthesis of functionalized benzofurans is achieved under mild and metal-free conditions from stable para-quinone methides by treatment with phosphine, acyl chloride, and a base. This one-pot phospha-1,6-addition/O-acylation/Wittig reaction i

A NEIGHBOURING GROUP PARTICIPATION OF ORTHO-METHOXYL GROUP IN SOLVOLYTIC REACTION OF SPIROOCTA-1,4,7-TRIEN-6-ONES

Ikeda, Toshihiko,Kobayashi, Shinjiro,Taniguchi, Hiroshi

, p. 391 - 394 (2007/10/02)

In aqueous ethanol 1-aryl-5,7-di-t-butyl-2-(o-methoxyphenyl)-spiroocta-1,4,7-trien-6-one 4 changed to 2-aryl-3-(3',5'-di-t-butyl-4'-hydroxyphenyl)benzofuran 5 in a more than 90percent yield.The selective formation of 5 is ascribed to a neighbouring group participation of the ortho-methoxyl group to an incipient vinyl cation.
