Abstract

TiCl4–Bu3N-mediated condensation of ketones with α, α-dimethoxyketones afforded trialkylsubstituted 2 (5H)-furanones in a one-pot manner, wherein aldol addition and furanone formation occurred sequentially; its application to straightforward synthesis of (R)- mintlactone and (R)-menthofuran, two representative natural mint perfumes, is demonstrated.
