Mild arylboronic acid catalyzed selective [4 + 3] cycloadditions: access to cyclohepta[b]benzofurans and cyclohepta[b]indoles.
نویسندگان
چکیده
The first example of arylboronic acid catalyzed [4 + 3] cycloaddition reaction is reported. 3,5-Bis-(trifluoromethyl) phenylboronic acid is shown to be the best catalyst in this reaction. The method has also enabled the preparation of cyclohepta[b]benzofurans and cyclohepta[b]indoles in excellent yields.

An Approach to Cyclohepta[b]indoles through an Allenamide (4 + 3) Cycloaddition–Grignard Cyclization–Chugaev Elimination Sequence
A strategy for synthesizing highly functionalized cyclohepta[b]indoles through a concise (4 + 3) cycloaddition-cyclization-elimination sequence is described. The cycloaddition features nitrogen-stabilized oxyallyl cations derived from epoxidations of N-aryl-N-sulfonyl-substituted allenamides, while the cyclization and elimination employed an intramolecular Grignard addition and a one-step Chuga...

Twenty-six benzocycloheptoxazine derivatives were investigated for their effect on nitric oxide (NO) production by lipopolysaccharide (LPS)-stimulated mouse macrophage-like RAW 264.7 cells. Benzo[b]cyclohepta[e][1,4]thiazine most effectively inhibited the LPS-stimulated NO production at noncytotoxic concentrations. 6H-Benzo[b]cyclohepta[e][1,4]-diazine cation, and benzo[b]cyclohepta[e][1,4]oxaz...
متن کاملNi(ClO4)(2)-catalysed regio- and diastereoselective [3+2] cycloaddition of indoles and aryl oxiranyl-dicarboxylates/diketones: a facile access to furo[3,4-b]indoles.
Ni(ClO(4))(2)·6H(2)O-catalysed regioselective and diastereoselective [3+2]-annulations of aryl oxiranyl-dicarboxylates and indoles via selective C-C bond cleavage of oxirane were revealed. The cycloadditions proceed smoothly with high regio- and diastereoselectivity under mild conditions leading to 1H-furo[3,4-b]indoles in good to excellent yields.

The polarity reversible nature of azomethine imines as the crucial transformation enables the tandem Michael addition/imine isomerization/[3+2] cycloaddition to proceed under mild, transition-metal-free conditions to form cyclohepta[b]pyrroles in a single operation starting from readily available acyclic precursors with a broad substrate scope.
