108380-28-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 108380-28-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,3,8 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 108380-28:
(8*1)+(7*0)+(6*8)+(5*3)+(4*8)+(3*0)+(2*2)+(1*8)=115
115 % 10 = 5
So 108380-28-5 is a valid CAS Registry Number.

Iridium-Catalyzed C-C Coupling of a Simple Propargyl Ether with Primary Alcohols: Enantioselective Homoaldol Addition via Redox-Triggered (Z)-Siloxyallylation

Liang, Tao,Zhang, Wandi,Krische, Michael J.

, p. 16024 - 16027 (2015)

A chiral iridium complex formed in situ from [Ir(cod)Cl]2 and (R)-H8-BINAP is found to catalyze the direct enantioselective C-C coupling of a simple propargyl ether, TIPSOCH2C-CH, with primary alcohols to form γ-hydroxy (Z)-enol silanes with uniformly high enantioselectivity and complete alkene (Z)-stereoselectivity. As corroborated by deuterium labeling studies, these studies represent the first examples of 1,2-hydride shift-enabled π-allyl formation in the context of iridium catalysis.

A direct method for the conversion of terminal epoxides into γ-butanolides

Movassaghi, Mohammad,Jacobsen, Eric N.

, p. 2456 - 2457 (2007/10/03)

A new and efficient process for the conversion of terminal epoxides to γ-butanolides is described involving Lewis acid promoted epoxide ring-opening by 1-morpholino-2-trimethylsilyl acetylene. Addition of a terminal epoxide to a solution of the ynamine an
