804530-53-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 804530-53-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,4,5,3 and 0 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 804530-53:
(8*8)+(7*0)+(6*4)+(5*5)+(4*3)+(3*0)+(2*5)+(1*3)=138
138 % 10 = 8
So 804530-53-8 is a valid CAS Registry Number.

Diastereoselective addition of zincated hydrazones to alkenylboronates and stereospecific trapping of boron/zinc bimetallic intermediates by carbon electrophiles

Hatakeyama, Takuji,Nakamura, Masaharu,Nakamura, Eiichi

, p. 15688 - 15701 (2008)

Zincated hydrazones possessing a tert-butyl group on the zinc atom undergo addition to (E)- or (Z)-alkenylboronic acid pinacol esters to produce α-alkylated-γ-boryl-γ-zinciohydrazone intermediates with good to excellent diastereoselectivity (ds). The 1,1 -organodimetallic intermediate possessing a boron atom and a zinc atom in the position γ to the hydrazone group undergoes further C-C bond formation with a carbon electrophile to give a γ-boryl hydrazone possessing several contiguous stereogenic centers with up to 99% ds. The (S)-1-amino-2-methoxymethylpyrrolidine hydrazone shows a high level of asymmetric induction in the addition/trapping sequence. Density functional theory calculations on the pathways of the addition reaction revealed a metallo-ene mechanism consisting of the formation of a π complex between a zincated hydrazone and a vinylborane followed by a six-centered bond reorganization of a highly ordered boat conformation transition state. The calculations indicated that the use of the zinc atom together with the imine or hydrazone is the key for the success of the olefinic variant of the aldol reaction that has long been considered not to take place because of the endothermicity of the reaction and has never been examined with any seriousness by chemists. The steric repulsion caused by the bulky tert-butyl ligand on the zinc atom and the pinacol moiety of the vinylboronate substrates in the highly ordered transition structures gives rise to the observed high ds of the present carbozincation reaction.

Sequential coupling of zincated hydrazone, alkenylboronate, and electrophile that creates several contiguous stereogenic centers

Nakamura, Masaharu,Hatakeyama, Takuji,Hara, Kenji,Fukudome, Hiroki,Nakamura, Eiichi

, p. 14344 - 14345 (2007/10/03)

A zincated N,N-dimethylhydrazone of a ketone undergoes stereospecific syn addition to E- or Z-alkenylboronate to generate a γ-Zn/B dimetallic intermediate, which reacts with a carbon electrophile to give a γ-borylhydrazone in good yield with excellent dia
