Calculate Digit Verification of CAS Registry Number 1469994-91:
(9*1)+(8*4)+(7*6)+(6*9)+(5*9)+(4*9)+(3*4)+(2*9)+(1*1)=249
249 % 10 = 9

Gated access to α-lithiated phenyltetrahydrofuran: Functionalisation via direct lithiation of the parent oxygen heterocycle

Mansueto, Rosmara,Mallardo, Valentina,Perna, Filippo Maria,Salomone, Antonio,Capriati, Vito

, p. 10160 - 10162 (2013/10/22)

Cycloreversion of α-lithiated phenyltetrahydrofuran was successfully tamed at -78 °C in a non-coordinating solvent in the presence of TMEDA. This anion showed excellent nucleophilicity and could be intercepted with a variety of structurally different electrophiles to give 2,2-disubstituted derivatives which can be further elaborated to γ-butyrolactones.
