Check Digit Verification of cas no

The CAS Registry Mumber 18075-42-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,0,7 and 5 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 18075-42:
(7*1)+(6*8)+(5*0)+(4*7)+(3*5)+(2*4)+(1*2)=108
108 % 10 = 8
So 18075-42-8 is a valid CAS Registry Number.

TBuO 2H/Cu(acac) 2-Mediated Intramolecular Oxidative Lactonization of o -Allyl Arylaldehydes: Synthesis of 1-Oxoisochromans

Chang, Meng-Yang,Lai, Kai-Xiang,Chen, Kuan-Ting

, p. 527 - 537 (2020/10/19)

A concise route for the tBuO 2H/Cu(acac) 2-mediated synthesis of 1-oxoisochromans is described. This includes: (i) oxidation of oxygenated o -allyl arylaldehydes and (ii) sequential intramolecular lactonization of the resulting olefin-containing benzoic acids. A plausible mechanism is proposed and discussed.

CuI Mediated One-Pot Cycloacetalization/Ketalization of o-Carbonyl Allylbenzenes: Synthesis of Benzobicyclo[3.2.1]octane Core

Chan, Chieh-Kai,Tsai, Yu-Lin,Chang, Meng-Yang

, p. 1870 - 1873 (2017/04/11)

CuI/DMSO-mediated intramolecular cycloacetalization/ketalization of o-carbonyl allylbenzenes has been achieved for constructing [6,6,5]-tricycles having a ketal motif in good yields. The expeditious one-step route provides a three C-O bond formation. The key products with the structural framework of a benzofused dioxabicyclo[3.2.1]octane core have been confirmed by X-ray crystallographic analysis. Synthesis of dihydroisocoumarin has been studied.

Synthesis of 2-hydroxymethyl-2,3-dihydrobenzofurans

Chang, Meng-Yang,Lin, Shin-Ying,Chanp, Chieh-Kai

, p. 1905 - 1912 (2014/08/18)

A one-pot protocol toward 2-hydroxymethyl-2,3-dihydrobenzofurans (1) starting with oxygenated o-allylbenzaldehydes (3) was described. The facile one-pot process was carried out by the oxidation of o-allylbenzaldehydes (3) with Oxone in the co-solvent of acetone and DMF in the presence of aqueous EDTA solution and then intramolecular ring-closure of the resulting o-allylphenols (2) in acceptable yields.

Synthesis of substituted indenes from isovanillin via claisen rearrangement and ring-closing metathesis

Huang, Keng-Shiang,Wang, Eng-Chi

, p. 383 - 391 (2015/02/05)

A new synthesis of substituted indenes was studied. Based on Claisen rearrangement,Wittig reaction and ring-closing metathesis (RCM), a series of substituted indenes was synthesized from isovanillin in good yields.

One-pot access to 2-naphthols and benzofurans via the aerobic Wacker-type oxidation/intramolecular aldol cyclization

Chang, Meng-Yang,Chan, Chieh-Kai,Lin, Shin-Ying

, p. 1532 - 1538 (2013/02/25)

An aerobic Wacker-type oxidation/intramolecular aldol cyclization synthetic route toward two oxygenated 2-naphthols 3 and benzofurans 4 starting with skeleton 2 with good yields is described. The route has been carried by the one-pot transformation of the regioselective PdCl2/CuCl 2-mediated Wacker oxidative cyclization of skeleton 2 with molecular oxygen under the alkaline methanolic condition. Skeleton 2 was prepared from skeleton 1 in moderate total yields via the known protocol.

Synthesis of dihydrobenzoimidazo[2,1-a]isoquinolines

Chang, Meng-Yang,Wu, Ming-Hao,Chen, Yeh-Long

scheme or table, p. 4156 - 4160 (2012/08/28)

A one-pot protocol toward several substituted 5,6-dihydrobenzo[4,5] imidazo[2,1-a]isoquinolines 1 starting with 2-allylbenzaldehydes 2 was described. The process was carried out the one-pot condensation/hydroamination reaction of substituted 2-allylbenzaldehydes 2 with 1,2-diaminobenzenes 3 in refluxing toluene in good yields. Skeleton 2 was prepared via one-pot ortho-metalative PhBCl2-mediated double alkylation of hydroxybenzaldehyde 4 with LDA in moderate yields.

Total synthesis of pulverolide: Revision of its structure

Yang, Wanqiu,Liu, Jikai,Zhang, Hongbin

supporting information; experimental part, p. 4874 - 4876 (2010/10/02)

A flexible and practical strategy toward the synthesis of rare 2H-furo[3,2-b]benzopyran-2-one skeleton has been developed. With a microwave-assisted cyclization-dehydration as the key transformation, the first total synthesis of pulverolide has been compl

Claisen rearrangement/Baylis-Hillman reaction/ring-closing metathesis as bases for the construction of substituted cyanonaphthalenes

, p. 2824 - 2828 (2007/10/03)

The present paper described how to establish a novel approach for various alkoxycyanonaphthalenes. It was started from isovanillin, and based on the Claisen rearrangement, O-alkylation, the Baylis-Hillman reaction, and ring-closing metathesis in sequence
