Abstract :
Scandium triflate efficiently catalyzes the cyclocondensation of o-hydroxybenzaldehydes with alkenes such as indene, styrene and allyltrimethylsilane in the presence of trimethyl orthoformate at ambient temperature to afford a new class of compounds, 2,4-disubstitued chromanes in high yields with high diastereoselectivity.
