Calculate Digit Verification of CAS Registry Number 959683-25:
(8*9)+(7*5)+(6*9)+(5*6)+(4*8)+(3*3)+(2*2)+(1*5)=241
241 % 10 = 1
So 959683-25-1 is a valid CAS Registry Number.

Vinylogous Mukaiyama-Michael Reactions of Dihydropyridinones

Li, Hui,Wu, Jimmy

, p. 5424 - 5427 (2015)

An In(III)-catalyzed vinylogous addition of O-silyl vinylketene acetals to 2,3-dihydro-4-pyridinones has been developed. The method features the unprecedented employment of supersilyl groups to influence the γ versus α regiochemical control of vinylogous Mukaiyama-Michael (vM-Michael) reactions when γ-substituted O-silyl vinylketene acetals are used. We also demonstrate that these reactions allow facile access to quinolizidine-based alkaloids such as deoxynupharidine and well as lasubine I and II.
