Catalytic asymmetric N-alkylation of indoles and carbazoles represents a family of important but underdeveloped reactions. Herein, we describe a new organocatalytic strategy in which in situ generated aza-para-quinone methides are employed as the alkylating reagent. With the proper choice of a chiral phosphoric acid and an N-protective group, the intermolecular C?N bond formation with various indole and carbazole nucleophiles proceeded efficiently under mild conditions with excellent enantioselectivity and functional-group compatibility. Control experiments and kinetic studies provided important insight into the reaction mechanism.

Photochemical oxidative cyclodehydrogenation reactions are a versatile class of aromatic ring-forming reactions. They are tolerant to functional group substitution and heteroatom inclusion, so can be used to form a diverse range of extended polyaromatic systems by fusing existing ring substituents. However, despite their undoubted synthetic utility, there are no existing models?computational or heuristic?that predict the outcome of photocyclisation reactions across all possible classes of reactants. This can be traced back to the fact that ?negative? results are rarely published in the synthetic literature and the lack of a general conceptual framework for understanding how photoexcitation affects reactivity. In this work, we address both of these issues. We present experimental data for a series of aromatically substituted pyrroles and indoles, and show that quantifying induced atomic forces upon photoexcitation provides a powerful predictive model for determining whether a given reactant will photoplanarise and hence proceed to photocyclised product under appropriate reaction conditions. The propensity of a molecule to photoplanarise is related to localised changes in charge distribution around the putative forming ring upon photoexcitation. This is promoted by asymmetry in molecular structures and/or charge distributions, inclusion of heteroatoms and ethylene bridging and well-separated or isolated photocyclisation sites.

Conjugated azoalkenes 2 react at reflux toluene with fused benzothiadiphosphole 1 (or 4) to give the diazaphosphole 3 in 25-52% yields. With this route it is possible to isolate the so far unknown 3a which is difficult to obtain in other reported conditions. The P atom involved in this cydoaddition is the one between the two S atoms.

Sodium deposited on inorganic supports such as Al2O3, TiO2 and NaCl (‘high-surface sodium’) is a cheap, readily prepared, nonpyrophoric reducing agent for TiCl3. The low-valent titanium thus obtained, after only 1 h reduction time, is well suited for McMurry coupling reactions, particularly of aromatic carbonyl compounds. It exhibits a previously unrivalled template effect for the cyclization of dicarbonyl compounds to (macrocyclic) cycloalkenes and is suitable for the reduction of N-acyl-2-aminobenzophenone derivatives to 2,3-disubstituted indoles. Even a 36-membered ring could be formed without recourse to high dilution techniques.

3-Hydroxy-3H-indoles (1) and their corresponding N-oxides (5) undergo stereospecific reduction at the double C=N bond giving the indoline derivatives (2) and (6) respectively, which, in acidic medium, lose water to give the 2,3-disubstituted indoles (3) and (7) whose physical and spectroscopic data are not in agreement with those reported previously.The structure of 3-hydroxy-2,3-diphenylindoline, one of the reduction products, was determined by X-ray diffraction, and it was shown that hydrogen adds at C-2 cis to the hydroxy-group on C-3. 3,3-Disubstituted-3H-indoles with two organic radicals on C-3 give a mixture of stereoisomers.

The reaction of indoles with copper(II) chloride has been studied in acetonitrile.At low copper(II):indole ratios, dimers are formed in the presence of dioxygen, oxygenated products are obtained, and at large copper(II):indole ratios, pyrrole ring-chlorinated products are formed in yields of up to 92percent.The reactions are postulated to proceed via the radical cations of the indoles formed in an electron-transfer reaction.

N-Formylindoles (1A-H) exhibit pronounced aldehydic character as revealed by the formation of 4-nitrophenylhydrazones (2A-E) and 2,4-dinitrophenylhydrazones (2F-J).The N-formylindoles (1E-G) bearing phenyl groups at 2- and 3-positions do not form either 4-nitrophenylhydrazones or 2,4-dinitrophenylhydrazones probably owing to steric hindrance.The N-formylindoles (1C-F) which bear a substituent at 2-position but none at 7-position exist only in one conformation, while those bearing either substituents at both 2- and 7-positions (i. e. 1G) or no substituent at all (i. e. 1A, 1B) exist in two conformations as shown by their PMR spectra.While the 4-nitrophenylhydrazones (2A-E) show expected fragmentation pattern, the 2,4-dinitrophenylhydrazones exhibit some interesting fragmentation pathways involving the successive loss of two OH radicals and N2 under electron impact.

Synthesis of indoles from aroyloxycarbamates with alkynes: Via decarboxylation/cyclization

An efficient Pd-catalyzed decarboxylation/cyclization of aroyloxycarbamates to realize substituted indoles has been disclosed. Terminal alkynes as the coupling partners lead to site specific 2-substituted indoles through two pathways, while internal alkynes with aroyloxycarbamates can be transformed to 2,3-disubstituted indoles directly. This protocol is further demonstrated by the efficient synthesis of indoles as well as the success of employing inexpensive aryl acids as starting materials to construct C-N bonds by releasing CO2.
