report of Lewisacid use in intramolecular Rauhut–Currier reactions is described. Titanium Lewisacids lead to rapid Rauhut–Currier reactions in the case of two classic substrates. More importantly, titanium and tin Lewisacids were the only successful reagent for a more complex substrate, thereby illustrating the potential for Lewisacid reagents to facilitate challenging intramolecular Rauhut–Currier

We describe the diversities of hydrolase-type enzymes PLE and HLE on the hydrolysis of (+/-)-methyl-2-methoxy-1 -methyl-2,5-cyclohexadiene-1-carboxylate and (+/-)-methyl-2-methoxy-1 -methyl-2,5-cyclohexadiene-4-one-1-carboxylate to afford both enantiomers with 92-96% ee.
