We have developed an efficient, simple, mild, and rapid method for the construction of dihydrobenzofuran derivatives by the [3+2] coupling of masked o-benzoquinones with styrene derivatives triggered by boron trifluoride diethyl etherate. This new [3+2] coupling protocol proceeds smoothly to afford dihydrobenzofuran derivatives in good to high yields within one minute. The method was extended to cycloaddition of p-benzoquinone monoketal with styrenes.

The studies on [4 + 2] cycloaddition of 4-halo derivatives of 6,6-dimethoxycyclohexa-2,4-dienones known as orthoquinone monoketals/masked o-benzoquinones are described. The 4-fluoro, 4-chloro- and 4-iodo-masked o-benzoquinones were stable enough for their
