Calculate Digit Verification of CAS Registry Number 930550-80:
(8*9)+(7*3)+(6*0)+(5*5)+(4*5)+(3*0)+(2*8)+(1*0)=154
154 % 10 = 4

Chlorotrimethylsilane mediated synthesis of 5-(2hydroxybenzoyl)pyrimidines from 3-formylchromones

Ryabukhin, Sergey V.,Plaskon, Andrey S.,Volochnyuk, Dmitriy M.,Pipko, Sergey E.,Tolmachev, Andrey A.

, p. 583 - 597 (2008/09/20)

The recyclization of 3-formylchromones with a variety of 1,3-NCNbinucleophiles promoted by chlorotrimethylsilane was investigated. A simple and flexible general procedure for the synthesis of series of 5-(2hydroxybenzoyl)pyrimidines and their heterofused analogues was proposed. A set of pyrimidines was obtained in high preparative yields.
