  Total synthesis of the marine natural products lukianols A and B

  摘要：

  Total synthesis of the pyrrolic marine natural products lukianols A (1) and B (2) has been achieved using N-benzenesulfonyl-3,4-dibromopyrrole (3) as a common starting material. The key synthetic strategy developed is the combined bromine-directed lithiation and palladium-catalyzed cross-coupling of 3 to produce 3,4-diarylpyrrol-2-carboxylates. Regioselective iodination of the phenolic intermediate 24 was thoroughly investigated for the synthesis of lukianol B. (C) 2013 Published by Elsevier Ltd.

  Palladium-catalyzed cross-coupling of N-benzenesulfonyl-3,4-dibromopyrrole and its application to the total syntheses of lamellarins O, P, Q, and R

  摘要：

  Palladium-catalyzed Suzuki-Miyaura Coupling of N-benzenesulfonyl-3,4-dibromopyrrole with a variety of arylboronic acids gave the corresponding 3,4-diarylpyrroles in high yields. The 3,4-differentially arylated pyrroles could also be prepared by stepwise cross-coupling approach. The total syntheses of lamellarins O, P, Q, and R have been achieved by using the cross-coupling and the directed lithiation as key reactions. (c) 2007 Elsevier Ltd. All rights reserved.

  electronic communication, where resonance structures significantly contribute to the thermodynamic stability of the cationic charges/spins and determine the spin multiplicities. For HPHAC 1 and pentaazacoronene 2, the overall aromaticity predicted for closed-shell dications 1(2+) and 2(2+) was primarily based on the theoretical calculations, and the open-shell singlet biradical or triplet character was anticipated
