An Efficient Synthesis of 2,2-Dimethylchromans from 4-Methoxy-2,2-dimethylchromans

Article abstract of DOI:10.1055/s-1990-26872

2,2-Dimethylchromans functionally substituted at C-7 were prepared by dealkoxylation of the corresponding 2,2-dimethyl-4-methoxychromans by catalytic hydrogenation on palladium on charcoal in acetic acid.
