Carbon dioxide is a green carboxylative reagent due to its non-toxic and renewable properties. Described herein is a carboxylative cyclization of substituted 1-propenyl ketones via γ-carboxylation using CO2, which provides an efficient, transit
Expedient synthesis of highly substituted α-pyrones from Baylis-Hillman adducts and their conversion to poly-substituted aromatics
Kim, Eun Sun,Kim, Ko Hoon,Kim, Sung Hwan,Kim, Jae Nyoung
scheme or table, p. 5098 - 5101 (2009/12/01)
An efficient synthetic protocol of fully substituted α-pyrones has been developed starting from the Baylis-Hillman adducts. Subsequent Diels-Alder reaction of the α-pyrones and DMAD produced poly-substituted aromatic compounds in high yields.
Rhenium- and manganese-catalyzed insertion of acetylenes into β-keto esters: Synthesis of 2-pyranones
Kuninobu, Yoichiro,Kawata, Atsushi,Nishi, Mitsumi,Takata, Hisatsugu,Takai, Kazuhiko
supporting information; experimental part, p. 6360 - 6362 (2009/04/13)
Rhenium- and manganese-catalyzed reactions between β-keto esters and acetylenes, followed by treatment with tetrabutylammonium fluoride, gave 2-pyranone derivatives regioselectively. The Royal Society of Chemistry 2008.
Novel 2-pyrone synthesis via the nucleophilic addition of active methine compounds to 2-alkynone
Hachiya, Iwao,Shibuya, Hitoshi,Shimizu, Makoto
, p. 2061 - 2063 (2007/10/03)
Novel 2-pyrone synthesis via the nucleophilic addition of active methine compounds to 2-alkynone has been developed. The reaction of active methine compounds with 2-alkynone provided 2-pyrones in good yields.
A synthesis of substituted 2-pyrones by carbonylative cross-coupling-thermolysis of 4-halocyclobutenones with alkenyl-, aryl-, and heteroarylstannanes
Liebeskind, Lanny S.,Wang, Jianying
, p. 5461 - 5470 (2007/10/02)
Palladium catalyzed carbonylative cross-coupling of 4-chloro-2,3-disubstituted-2-cyclobutenones with alkenyl-, aryl-, and heteroaryltin reagents and thermolysis provides a general method for the synthesis of 2,3,6-trisubstituted-2-pyrones. The reaction is
