Abstract
1,4-Benzoquinones undergo smoothly [3 + 2] cycloaddition reactions with electron rich alkenes in the presence of 10 mol% indium trichloride or 5 mol% iodine under mild conditions to afford the corresponding 2,3-dihydrobenzofurans in excellent yields with trans-selectivity. Similarly, methyl vinyl ketone reacts with electron rich olefins to produce substituited trans-cyclobutane derivatives.
Key words
indium reagents - iodine - p-quinones - alkenes - benzofurans
