110550-26-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 110550-26-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,5,5 and 0 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 110550-26:
(8*1)+(7*1)+(6*0)+(5*5)+(4*5)+(3*0)+(2*2)+(1*6)=70
70 % 10 = 0
So 110550-26-0 is a valid CAS Registry Number.

N-heterocyclic carbene-catalyzed benzoin strategy for divergent synthesis of cyclitol derivatives from alditols

Kang, Bubwoong,Sutou, Toshiaki,Wang, Yinli,Kuwano, Satoru,Yamaoka, Yousuke,Takasu, Kiyosei,Yamada, Ken-Ichi

, p. 131 - 147 (2015/01/30)

A divergent synthesis of cyclitol derivatives has been developed utilizing an N-heterocyclic carbene-catalyzed benzoin-type cyclization of C2-symmetrical dialdoses. The resulting inososes are versatile intermediates, which are readily converted

Relative reactivity of hydroxyl groups in inositol derivatives: role of metal ion chelation

Devaraj, Subramanian,Jagdhane, Rajendra C.,Shashidhar, Mysore S.

experimental part, p. 1159 - 1166 (2009/10/04)

O-Alkylation of myo-inositol derivatives containing more than one hydroxyl group via their alkali metal alkoxides (sodium or lithium) preferentially occurs at a hydroxyl group having a vicinal cis-oxygen atom. In general the observed selectivity is relatively higher for lithium alkoxides than for the corresponding sodium alkoxide. The observed regioselectivity is also dependent on other factors such as the solvent and reaction temperature. A perusal of the results presented in this article as well as those available in the literature suggests that chelation of metal ions by inositol derivatives plays a significant role in the observed regioselectivity. Steric factors associated with the axial or equatorial disposition of the reacting hydroxyl groups do not contribute much to the outcome of these O-alkylation reactions. These results could serve as guidelines in planning synthetic strategies involving other carbohydrates and their derivatives.

Stable axial-rich chair conformer of myo-inositol derivatives due to introduction of two adjacent bulky silyl protections

Yamada, Hidetoshi,Okajima, Kotaro,Imagawa, Hiroshi,Mukae, Tatsuya,Kawamura, Yoshiaki,Nishizawa, Mugio

, p. 3157 - 3160 (2007/10/03)

The ring-conformational change of myo-inositol derivatives by introducing two tert-butyldimethylsilyl, triisopropylsilyl, or tert-butyldiphenylsilyl groups into the 1,2-trans hydroxy groups - 3,4- and 4,5-positions - were investigated. The cyclohexane cores of the 4,5-bis-O-silylated derivatives with tert-butyldiphenylsilyl or triisopropylsilyl groups were present in the axial-rich chair form.
