One-pot synthesis of α-methyl ketones starting from 1,3-diaryl propenols or 1-aryl propenols and methanol as a C1 source is demonstrated. This one-pot isomerization-methylation is catalyzed by commercially available Pd(OAc)2 with H2O as the only by-product. Mechanistic studies and deuterium labelling experiments indicate the involvement of isomerization of allyl alcohol followed by methylation through a hydrogen-borrowing pathway in these isomerization-methylation reactions.

Upon irradiation a regio- and stereoselective cycloaddition occured intramolecularly between two acyl-1,4-benzoquinone moieties connected by a polymethylene bridge.The regio- and stereoselectivities are different from those of the corresponding intermolecular cycloaddition; this was interpreted in terms of the Diels-Alder reaction between an acyl-1,4-benzoquinone moiety and a photochemically produced dienol.

Two novel hallucinogen analogues related to 1-(2,5-dimethoxy-4-methylphenyl)-2-aminopropane (DOM, STP) were synthesized and evaluated in the two-lever drug discrimination paradigm by using 0.08 mg/kg of LSD at the training drug stimulus.The two compounds
Benzoquinones and Related Compounds. Part 2. Preferred Conformations of Some Acyl-1,4-benzoquinones in Solution

Studies based on polarographic reduction potentials, electronic absorption spectra, and (1)H and (13)C nuclear magnetic relaxation data show that in solution the preferred conformation of formyl-1,4-benzoquinone is that with the formyl and quinonoid groups coplanar, and the formyl carbonyl group anti to the 1-carbonyl, whereas that of acetyl- and pivaloyl-1,4-benzoquinone has the acyl groups approximately perpendicular to the quinonoid ring.
