Calculate Digit Verification of CAS Registry Number 1431884-74:
(9*1)+(8*4)+(7*3)+(6*1)+(5*8)+(4*8)+(3*4)+(2*7)+(1*4)=170
170 % 10 = 0

Light-induced stereospecific intramolecular [2+2]-cycloaddition of atropisomeric 3,4-dihydro-2-pyridones

Kumarasamy, Elango,Sivaguru

supporting information, p. 4346 - 4348 (2013/06/27)

Atropisomeric 3,4-dihydro-2-pyridones undergo stereospecific [2+2]-photocycloaddition in solution with high stereoselectivity (ee > 98% and de > 96%) in the product. The chiral transfer during phototransformation was rationalized based on the stability/reactivity of the biradical.
