Correction for “Novel pathways for fuels and lubricants from biomass optimized using life-cycle greenhouse gas assessment,” by Madhesan Balakrishnan, Eric R. Sacia, Sanil Sreekumar, Gorkem Gunbas, Amit A. Gokhale, Corinne D. Scown, F. Dean Toste, and Alexis T. Bell, which appeared in issue 25, June 23, 2015, of Proc Natl Acad Sci USA (112:7645–7649; first published June 8, 2015; 10.1073/pnas.1508274112).

The authors note that Table 1 appeared incorrectly. The corrected table appears below.

Table 1.

Self-condensation of ketones in the presence of solid acid/base catalysts

Ketone (1, 2 mmol), catalyst (200 mg) and toluene (3 mL) was heated in a sealed Q-tube reactor. Conv.1, conversion of compound 1.

^*Mixture of positional and stereoisomers.

^†Catalyst MgAlO represents calcined Mg/Al-hydrotalcite (Mg/Al = 3:1) and Nb₂O₅ represents calcined niobic acid.

^‡Cyclohexane (3 mL) was used as solvent.
