Palladium(II)-Catalyzed annulation between ortho-alkenylphenols and allenes. Key role of the metal geometry in determining the reaction outcome
(American Chemical Society, 2016-04-14)2-Alkenylphenols react with allenes, upon treatment with catalytic amounts of Pd(II) and Cu(II), to give benzoxepine products in high yields and with very good regio- and diastereoselectivities. This contrasts with the ... -
Rh(III)-catalyzed annulations based on C-H activation. Sustainable synthesis of carbo- and heterocycles
(2016)One of the main challenges still present within organic synthesis is the ability to achieve complex molecules with high efficiency. In this context metal-catalyzed C-H functionalization processes have gained a lot of ... -
Rhodium(III)‐Catalyzed Annulation of 2‐Alkenylanilides with Alkynes via C‐H Activation: a Direct Access to 2‐substituted Indolines
(Wiley, 2018-05-04)A Rh(III) complex featuring an electron‐deficient η5‐cyclopentadienyl ligand catalyzes an unusual annulation between alkynes and 2‐alkenylanilides, to form synthetically appealing 2‐substituted indolines. Formally, the ... -
Rhodium-Catalyzed (5+1) Annulations Between 2-Alkenylphenols and Allenes: A Practical Entry to 2,2-Disubstituted 2H-Chromenes
(WILEY-VCH Verlag GmbH, 2015-01-07)Readily available alkenylphenols react with allenes under rhodium catalysis to provide valuable 2,2-disubstituted 2H-chromenes. The whole process, which involves the cleavage of one C-H bond of the alkenyl moiety and the ...
