Palladium catalysed tetramolecular queuing cascades of aryl iodides, carbon monoxide, amines and a polymer supported allene
Grigg,MacLachlan,Rasparini
, p. 2241 - 2242 (2000)
Chemo- and regio-specific palladium catalysed four component processes, involving formation of 3 new bonds, initiated by oxidative addition of Pd(0) with aryl iodides followed by sequential incorporation of CO (1 atm), a polymer supported allene and an am

We report the synthesis of a 2-phosphinoimidazole-derived bimetallic Rh(II) complex that enables intramolecular allene hydroamination to form 7- to 10-member rings in high yield. Monometallic Rh complexes, in contrast, fail to achieve any product formatio
Enantioselective Rhodium-Catalyzed Dimerization of ω-Allenyl Carboxylic Acids: Straightforward Synthesis of C2-Symmetric Macrodiolides
Steib, Philip,Breit, Bernhard
, p. 6572 - 6576 (2018/05/08)
Herein, we report on the first enantioselective and atom-efficient catalytic one-step dimerization method to selectively transform ω-allenyl carboxylic acids into C2-symmetric 14- to 28-membered bismacrolactones (macrodiolides). This convenient asymmetric access serves as an attractive route towards multiple naturally occuring homodimeric macrocyclic scaffolds and demonstrates excellent efficiency to construct the complex, symmetric core structures. By utilizing a rhodium catalyst with a modified chiral cyclopentylidene-diop ligand, the desired diolides were obtained in good to high yields, high diastereoselectivity, and excellent enantioselectivity.
Stereoselective synthesis of chiral polycyclic indolic architectures through Pd0-catalyzed tandem deprotection/cyclization of tetrahydro-β-carbolines on allenes
Gobé, Valérian,Guinchard, Xavier
, p. 8511 - 8520 (2015/06/02)
Enantioenriched N-allyl tetrahydro-β-carbolines were prepared by chiral phosphoric acid-catalyzed Pictet-Spengler reactions. The compounds undergo Pd0-catalyzed cyclizations through a tandem deprotection/cyclization process. The regioselectivit
