A new synthesis of o-prenyl phenols
Abstract
Phenylthiyl radicals add regiospecifically to isoprenoid chrom-3-enes to yield 3-phenylthiochromans which open to o-prenylphenols on electron transfer from metal naphthalenides or a mercury cathode; the two–step process is tolerant of free phenol and carbonyl functions, and trisubstituted double bonds.
