Radical reactions leading to substituted coumarins
摘要:
The reaction of 4-hydroxycoumarins with a series of quinonic chlorides under photostimulation was shown to provide an efficient approach to 3-alkylated coumarin derivatives, Alkylation reactions of this type proceeded via an electron transfer mechanism (S(RN)1).

Syntheses of coenzyme Q(3-8) are described, as well as related systems such as plastoquinone-5. Preparation of thr higher homologues of the ubiquinones relies on two new conjunctive reagents, or "linchpins", each of which ultimately corresponds to two or three prenyl units. These allow for attachment of a polyprenyl halide at one end, followed by a Ni(0)-catalyzed cross-coupling at the other terminus with a chloromethylated p-quinone.
