Rochais, Christophe published the artcileOne-pot synthesis of new aza- and diaza-aminophenanthrenes, Safety of Methyl 2-(2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)acetate, the publication is Tetrahedron (2011), 67(32), 5806-5810, database is CAplus.

The synthesis of a series of benzo(iso)quinoline and phenanthroline derivatives has been achieved using an efficient one-pot procedure. It proceeds through a Suzuki-Miyaura cross-coupling followed by a Dieckmann-Thorpe ring closure under microwave irradiation and provides easy access to building blocks not readily available through other methods.

Lawer, Aggie published the artcileInternal Nucleophilic Catalyst Mediated Cyclisation/Ring Expansion Cascades for the Synthesis of Medium-Sized Lactones and Lactams, COA of Formula: C15H21BO4, the publication is Angewandte Chemie, International Edition (2019), 58(39), 13942-13947, database is CAplus and MEDLINE.

A strategy for the synthesis of medium-sized lactones and lactams from linear precursors is described in which an amine acts as an internal nucleophilic catalyst to facilitate a novel cyclisation/ring expansion cascade sequence. This method obviates the need for the high-dilution conditions usually associated with medium-ring cyclisation protocols, as the reactions operate exclusively via kinetically favorable “normal”-sized cyclic transition states. This same feature also enables biaryl-containing medium-sized rings to be prepared with complete atroposelectivity by point-to-axial chirality transfer.

Yougnia, Rodrigue published the artcileOne-pot synthesis of novel poly-substituted phenanthrenes, Product Details of C15H21BO4, the publication is Tetrahedron (2010), 66(15), 2803-2808, database is CAplus.

A one-pot synthesis of novel poly-substituted phenanthrenes is described in this article through a Suzuki-Miyaura cross-coupling followed by a Dieckmann-Thorpe ring closure under microwave irradiation The selection of the appropriate starting materials allowed us to introduce diversity on various positions of the phenanthrene ring system.

Tsukamoto, Hirokazu published the artcilePalladium(II)-Catalyzed Annulation of Alkynes with ortho-Ester-Containing Phenylboronic Acids, COA of Formula: C15H21BO4, the publication is Organic Letters (2007), 9(21), 4227-4230, database is CAplus and MEDLINE.

Palladium(II) catalyzes annulation of internal alkynes with Me 2-boronobenzoate and (2-boronophenyl)acetate to provide 2,3-disubstituted indenones and 3,4-disubstituted 2-naphthols, resp. E.g., [1,2-bis(diphenylphosphino)ethane]palladium(II) ditrifluoroacetate catalyzed the reaction of 2-methoxycarbonylphenylboronic acid with bis(4-methoxyphenyl)acetylene to give 98% indenone I. The annulation reaction would proceed through transmetalation of Pd(II) with the boron reagents and insertion of the alkynes, followed by unprecedented 1,2-addition of the generated alkenylpalladium(II) species to the intramol. ester group.

In the presence of [RhCl(coe)]₂ and nonracemic bicyclooctadienecarboxamide I, internal aryl alkynes such as 1-(1-propynyl)naphthalene with ortho-substituted aryl moieties underwent regioselective and enantioselective cyclization reactions with o-(pinacolboronato)phenylacetonitriles mediated by K₃PO₄ in aqueous 1,4-dioxane to yield nonracemic biarylamines such as binaphthylamine II with stereogenic axes in 72-97% ee (all but one compound formed in >90% ee).

Aiken, Stuart published the artcileAn intramolecular, Pd-mediated α-arylation route to 4-aryl-2-naphthols, Recommanded Product: Methyl 2-(2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)acetate, the publication is Tetrahedron Letters (2015), 56(33), 4840-4842, database is CAplus.

1-Aryl-1-(2-bromophenyl)but-2-yn-1-ols, obtained from the addition of prop-1-yn-1-yllithium to 2-bromobenzophenones, readily rearrange to 4-aryl-4-(2-bromophenyl)but-3-en-2-ones upon treatment with TFA. Subsequent intramol. Pd-mediated α-arylation of these but-3-en-2-ones gave 4-aryl-2-naphthols which were smoothly transformed into photochromic naphthopyrans.
