✦ Synopsis

The authors regret to the wrong signal described in the manuscript according to the optical rotations of compounds 12a and 12b. It was described in the text: 'Using the higher amount of oxidizing agent, (+)-12a was obtained in 82% yield, and (+)-12b in 75% yield.'

The correct phrase should be 'Using the higher amount of oxidizing agent, (À)-12a was obtained in 82% yield, and (À)-12b in 75% yield.
