Direct Copper-Catalyzed Three-Component Synthesis of Sulfonamides

First introduced into medicines in the 1930s, the sulfonamide functional group continues to be present in a wide range of contemporary pharmaceuticals and agrochemicals. Despite their popularity in the design of modern bioactive molecules, the underpinning methods for sulfonamide synthesis are essentially unchanged since their introduction, and rely on the use of starting materials with preinstalled sulfur-functionality. Herein we report a direct single-step synthesis of sulfonamides that combines two of the largest monomer sets available in discovery chemistry, (hetero)aryl boronic acids and amines, along with sulfur dioxide, using a Cu(II) catalyst, to deliver a broad range of sulfonamides. Sulfur dioxide is provided by the surrogate reagent DABSO. The reaction tolerates broad variation in both coupling partners, including aryl, heteroaryl and alkenyl boronic acids, as well as cyclic and acyclic alkyl secondary amines, and primary anilines. We validate the method by showing that a variety of drugs, and drug-fragments, can be incorporated into the process.

Convergent catalytic asymmetric synthesis of camptothecin analog GI147211C

The topoisomerase I inhibitor GI147211C (4) was discovered at Glaxo Wellcome and shown to have promising anti-cancer properties. In order to fully assess the clinical potential of 4, an improved synthesis of the drug substance was required. Herein is described a convergent catalytic asymmetric synthesis of 4 which utilizes as key steps, two Heck reactions, a Sharpless asymmetric dihydroxylation reaction, and a Mitsunobu reaction. A 2-chloroquinoline is shown to be a viable substrate for the final Heck reaction to generate the camptothecin nucleus.

Synthetic Approaches to Phthalazines: C-N Bond Cleavage in 2′-Benzylbenzohydrazides During Reaction with Polyphosphoric Acid

Reaction of 2′-benzylbenzohydrazides with concentrated polyphosphoric acid gave 2,5-diaryl-1,3,4-oxadiazoles and a polybenzyl.Cyclodehydration to phthalazines was not observed.It is inferred from product substitution patterns that CH2-N bond cleavage occurs with polybenzyls forming from the benzyl moiety and oxadiazoles from the benzohydrazide fragment.Other reported reactions which generate benzyl fragments lead to bibenzyl and are considered to involve trapping of the cleavage products within a solvent cage.The observed production of polybenzyls is therefore interpreted in terms of the formation of free benzyl fragments.A tetrahydrophthalazine derivative was produced from the addition of diethyl azodicarboxylate to the photodiene of o-methylbenzophenone, but this could not be converted into a phthalazine.

Synthesis and biological evaluation of a series of benzoxazole/ benzothiazole-containing 2,3-dihydrobenzo[b][1,4]dioxine derivatives as potential antidepressants

A series of benzoxazole/benzothiazole-2,3-dihydrobenzo[b][1,4]dioxine derivatives (5a-5d and 8a-8j) was synthesized. Compounds were evaluated for binding affinities at the 5-HT1A and 5-HT2A receptors. Antidepressant activities of the compounds were screened using the forced swimming test (FST) and the tail suspension test (TST). The results indicated that the compounds exhibited high affinities for the 5-HT1A and 5-HT2A receptors and showed a marked antidepressant-like activity. Compound 8g exhibited high affinities for the 5-HT1A (Ki = 17 nM) and 5-HT2A (Ki = 0.71 nM) receptors; it also produced a decrease of the immobility time and exhibited potent antidepressant-like effects in the FST and TST in mice.

A Direct Synthesis of 2-(omega-Carboxyalkyl)isoflavones from ortho-Hydroxylated Deoxybenzoins

As part of a program focused on the development of new antineoplastic agents based on scaffolds found in natural products, we explored the isoflavone family as potential enzyme inhibitors. We required biotin-modified isoflavones to identify potential biological targets, and we selected the C-2 position in isoflavones as an attachment site for an alkyl group bearing a terminal carboxylic acid to which we could attach a biotin derivative. The base-catalyzed condensation of 2,4-dihydroxy-substituted deoxybenzoins with cyclic anhydrides mediated by a combination of triethylamine and 1,8-diazabicyclo[5.4.0]undec-7-ene led to an efficient synthesis of the desired 2-(omega-carboxyalkyl)isoflavones with functional groups at C-5, 6 and 7 and with various substituents in the C-3 phenyl group.

Direct synthesis of ethers from aldehydes and ketones. One-pot reductive etherification of benzaldehydes, alkyl aryl ketones, and benzophenones

Benzyl alcohols formed by the reduction of benzaldehydes, alkyl aryl ketones, and benzophenones with sodium tetrahydridoborate in alcohols undergo in situ etherification with the solvent in the presence of a catalytic amount of HCl. Thus the process may be regarded as one-pot transformation of carbonyl compounds into the corresponding benzyl ethers. The yields of ethers depend on the substituent nature in the aromatic fragment of the initial carbonyl compound and on the alcohol used as reduction medium.
