Calculate Digit Verification of CAS Registry Number 1374419-05:
(9*1)+(8*3)+(7*7)+(6*4)+(5*4)+(4*1)+(3*9)+(2*0)+(1*5)=162

Dinuclear zinc catalyzed asymmetric spirannulation reaction: An umpolung strategy for formation of α-alkylated-α-hydroxyoxindoles

Trost, Barry M.,Hirano, Keiichi

supporting information; experimental part, p. 2446 - 2449 (2012/07/27)

A highly diastereo- and enantioselective formal [3 + 2] cycloaddition of α,β-unsaturated esters and 3-hydroxyoxindoles catalyzed by a dinuclear zinc-ProPhenol complex is reported. The stereoselective Michael additions of 3-hydroxyoxindoles and the subsequent transesterifications afford spirocyclic δ-lactones.
