Direct palladium-catalyzed selective monoallylation of anilines using allylic alcohols
摘要:
N-Allylation of anilines using allylic alcohols directly to give monoallylic anilines selectively in high yields has been realized by employing palladium acetate-triphenylphosphine as the catalyst. Palladium-catalyzed one-pot cyclization of 2-aminophenols with 2-butene-1,4-diol leads to 3,4-dihydro-2-vinyl-2H-1,4-benzoxazines. (C) 2000 Elsevier Science Ltd. All rights reserved.

approach for the construction of novel bicyclic fused cyclopentenones starting from Morita–Baylis–Hillman (MBH) acetates of acetylenic aldehydes with flexible scaffold diversity has been achieved using a two-step reaction sequence involving allylic substitution and the Pauson–Khand reaction. This strategy provided a facile access to various bicycliccyclopentenones fused with either a carbocyclic or a

The direct activation of C-O bonds in allyl alcohols by palladium complexes has been accelerated by carrying out the reactions in the presence of titanium(IV) isopropoxide and 4A molecular sieves. N-Allylation of anilines to give mono- and diallylanilines using allyl alcohols directly has been realized by employing palladium catalysts. (C) 1999 Elsevier Science Ltd. All rights reserved.

A single-step synthesis of 3-hydroxycarbazoles has been achieved via annulation of electron-rich anilines and quinones in PhMe/AcOH (4:1) at room temperature. This chemistry tolerates various substituted benzoquinones and naphthoquinones, however, is sensitive to both the electronic and steric properties of the anilines. The desired 3-hydroxycarbazole derivatives are generally produced in moderate
