Berkeley's Dean Toste showcased the metal's catalytic utility throughout the year, using gold to turn simple alkene precursors into complex cyclic molecules[1], including fawcettimine - the first asymmetric synthesis of this natural product coming almost 50 years after its discovery[2]. This developed chemistry is anticipated to have wider application in total syntheses of many other natural products. Toste also David MacMillan at Princeton dramatically expanded the power of organocatalysis with his SOMO (singly occupied molecular orbital) strategy (CW May p24).
