Cycloadditions with clays and alumina without solvents
摘要:
The utilization of unactivated K-10 montmorillonite or alumina for Diels-Alder reactions in the absence of solvents, either with symmetrically-or unsymmetrically-substituted carbonyl dienophiles, constitutes an environmentally-friendly alternative providing excellent selectivities under mild conditions.
