Sustainable and selective synthesis of 3,4-dihydroquinolizin-2-one and quinolizin-2-one derivatives via the reactions of penta-3,4-dien-2-ones

In this paper, a novel and green methodology for the synthesis of 3,4-dihydroquinolizin-2-one derivatives via the tandem reactions of penta-3,4-dien-2-ones with pyridine, quinoline, or isoquinoline at rt in aqueous ethanol was developed. Notably, the reac

One-pot cascade reactions of 1-arylpenta-3,4-dien-2-ones leading to 2-arylphenols and dibenzopyroanones

A one-pot cascade reaction of 1-arylpenta-3,4-dien-2-ones with activated ketones allowed for an efficient and sustainable synthesis of 2-arylphenols. Moreover, this reaction was also found to be compatible and combinable with Pd-catalyzed C-H activation a

Mercury(II)-Catalyzed Synthesis of Spiro[4.5]decatrienediones from Allenyl Ketones and Comparison with Silver(I)-, Palladium(II)- and Bronsted Acid-Catalyzed Reactions

The allenyl p-methoxybenzyl ketone 3a and allenyl p-siloxybenzyl ketones 6b selectively delivered three different products with three different transition metal-catalysts. With Hg(II)-catalysts a spiro[4.5]decene 9, with Ag(I)-catalysts a 2-substituted furan (10/11) and with Pd(II)-catalysts a 2,4-disubstituted furan (8/12) was formed. Only with perchloric acid the intermolecular addition of water to the allene, leading to 1,3-dicarbonyl compounds 7, was observed. While with the corresponding allenyl o-methoxybenzyl ketone 3b the Ag(I)- and Pd(II)-catalysts provided the expected products, the mercury-catalyst led to a new and interesting side-product rac-17 which combined both the furan moiety and the spiro[4.5]decene moiety. Efforts to prepare allenyl hydroxybenzyl ketones failed, in one case a small amount of a 5H-benzo[b]oxepin-4-one 21 was isolated. It also was not possible to extend the spirocyclization to allenyl p-siloxyphenyl ketone 6a or allenyl 2-(p-siloxyphenyl)ethyl ketone 6c.
