115693-78-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 115693-78-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,6,9 and 3 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 115693-78:
(8*1)+(7*1)+(6*5)+(5*6)+(4*9)+(3*3)+(2*7)+(1*8)=142
142 % 10 = 2
So 115693-78-2 is a valid CAS Registry Number.

A practical method for p -methoxybenzylation of hydroxy groups using 2,4,6-tris(p -methoxybenzyloxy)-1,3,5-triazine (TriBOT-PM)

Yamada, Kohei,Fujita, Hikaru,Kitamura, Masanori,Kunishima, Munetaka

, p. 2989 - 2997 (2013/11/06)

A new acid-catalyzed p-methoxybenzylating reagent, 2,4,6-tris(p- methoxybenzyloxy)-1,3,5-triazine (TriBOT-PM), has been developed. The reaction of acid- and alkali-labile alcohols with TriBOT-PM in the presence of a catalytic amount of various acids (TfOH, BF3·OEt2, CSA, etc.) afforded the corresponding p-methoxybenzyl ethers in good yields. Since TriBOT-PM is an air-stable crystalline solid and can be prepared from inexpensive materials, i.e. cyanuric chloride and anisyl alcohol, this route is of practical use. Georg Thieme Verlag Stuttgart, New York.

An efficient means for generating p-methoxybenzyl (PMB) ethers under mildly acidic conditions

Stewart, Catherine A.,Peng, Xiaowen,Paquette, Leo A.

, p. 433 - 437 (2008/09/20)

The protection of a wide variety of alcohols as their p-methoxybenzyl ethers can be performed with PMBO-lepidine in the presence of methyl tosylate or, preferably, camphorsulfonic acid. No inorganic promoters are required, thereby facilitating workup and product isolation. Georg Thieme Verlag Stuttgart.

An efficient method for the p-methoxybenzylation of hydroxy groups with 2-(4-methoxybenzyloxy)-3-nitropyridine

Nakano, Masakazu,Kikuchi, Wataru,Matsuo, Jun-Ichi,Mukaiyama, Teruaki

, p. 424 - 425 (2007/10/03)

2-(4-Methoxybenzyloxy)-3-nitropyridine (PMBONPy), easily prepared from 2-chloro-3-nitropyridine and p-methoxybenzyl (PMB) alcohol, reacts with various types of hydroxy groups in the presence of a catalytic amount of trimethylsilyl triflate (Me3SiOTf) to give the corresponding PMB ethers in high yields under mild conditions.
