Bifunctional building blocks in the Ugi-azide condensation reaction: A general strategy toward exploration of new molecular diversity
Gunawan, Steven,Hulme, Christopher
supporting information, p. 6036 - 6046 (2013/09/12)
1,5-Disubstituted tetrazoles are an important drug-like scaffold known for their ability to mimic the cis-amide bond conformation. The scaffold is readily accessible via substitution of the carboxylic acid component of the Ugi multi-component reaction (MCR) with TMSN3 in what is herein denoted the Ugi-azide reaction. This full paper presents a concise, novel, general strategy to access a plethora of new heterocylic scaffolds utilizing tethered aldo/keto-acids/esters in the Ugi-azide reaction followed by a ring closing event that generates novel highly complex bis-heterocyclic lactam-tetrazoles.

An exceptionally stereoselective and general synthesis of (Z)-α-haloacrylates, ready to undergo various synthetic transformations, has been demonstrated from α-haloacetates and aldehydes in a one-pot manner via the titanium-enolate based asymmetric aldol
Potash alum [KAL(SO4)2.12H2O] catalysed esterification of formylphenoxyaliphatic acids
Shunmugadhas, Ganesan,Kumar, Suresh,Kumaresan, Sudalaiandi
, p. 857 - 863,7 (2020/09/09)
A convenient and clean procedure for esterification is reported. Direct condensation of formylphenoxyaliphatic acids with low to high boiling alcohols catalysed by potash alum gave moderate to good yields. This catalyst could be recovered and reused without substantial loss in its catalytic activity and the methodology could be used for a range of closely related substrates.

Compounds for treatment of cardiac arrhythmia synthesis, and methods of use
-
, (2008/06/13)
The subject invention pertains to novel compounds, and compositions comprising the compounds, for the treatment of cardiac arrhythmias. The subject invention further concerns a method of making the novel compounds. The novel compounds are rapidly metabolized analogs of amiodarone, having the distinct and advantageous characteristic of being metabolized to a less lipophilic compound. The new compounds can have particular utility for treating life-threatening ventricular tachyarrhythmias, especially in patients with congestive heart failure (CHF). The product can also provide effective management for ventricular arrhythmias and supraventricular arrhythmias, including atrial fibrillation and re-entrant tachyarrhythmias involving accessory pathways.

Synthesis of Aryloxy Analogues of Arachidonic Acid via Wittig and Palladium Catalysed Cross-coupling Reactions

, p. 3144 - 3177 (2007/10/02)
The synthesis of o- and p-phenoxy analogues of arachidonic acid is described.In particular, the Wittig olefination reaction of hydroxy and alkyloxy benzaldehydes has been investigated and the products shown to be highly dependent on the solvent used.E/Z isomer control was difficult to achieve in most cases, although there was a tendency towards Z-isomer formation in dimethyl sulphoxide compared to tetrahydrofuran, particularly for the phenolic compounds.Specific Z-isomer formation was achieved by the partial reduction of alkynes derived from appropriately protected bromophenols via Heck or palladium catalysed cross-coupling reactions.
