Calculate Digit Verification of CAS Registry Number 1474048-85:
(9*1)+(8*4)+(7*7)+(6*4)+(5*0)+(4*4)+(3*8)+(2*8)+(1*5)=175
175 % 10 = 5

Weinreb Amide based building block for convenient access to vinyl ketones

Tiwari, Praveen Kumar,Aidhen, Indrapal Singh

, p. 1777 - 1780 (2013/09/12)

A new strategy for the synthesis of vinyl ketones has been achieved. Hitherto unknown and easily accessible, β-phenylseleno-N-methoxy-N- methylpropanamide, obtained through two simple reactions, served as a building block for convenient access to vinyl ketones. The N-methoxy-N-methyl amide moiety ensured no overaddition of the Grignard reagent and, hence, the excellent formation of β-phenylseleno ketones; oxidative work-up with hydrogen peroxide provided ready access to the vinyl ketones with concomitant loss of phenylselanol.
