• and successive treatment with 1 M HCl gave 2-cyanonaphthalen-1-ols or 3-(3-cyanoethyl)phthalides. On the other hand, the reaction of 2-acylbenzoates with methyl vinyl ketone under the same conditions produced 3-(3-oxobutyl)phthalides as the sole products. What determines the product selectivity was

• context, we report here that the electroreduction of o-acylbenzoates 1 with acrylonitrile (2a) in the presence of TMSCl and subsequent treatment with 1 M HCl gives 2-cyanonaphthalen-1-ols 3 or 3-(3-cyanoethyl)phthalides 4 (Scheme 3). The product selectivity depends on the position of the methoxy
