Abstract
From what began as a casual discovery of the ketene-Claisen rearrangement (the Malherbe-Belluš rearrangement) over 3 decades ago has flourished a reaction of substantial significance. The noticeable qualities of the ketene-Claisen...
The chemical components of essential oils derived from leaves and flowers of Lantana camara growing in Saudi Arabia are analyzed for the first time using gas chromatography techniques (GC–MS, GC–FID, Co-GC, LRI determination, and database and...
Pharmacological Applications of Quercetin and its Derivatives: A Short Review
The lithiation of 2-(2,2-dimethyl-1,3-dioxolan-4-yl)ethyl diisopropylcarbamate (1) is achieved freely by sec-butyllithium in diethylether with high lk-diastereoselectivity: the bicyclic chelate complexes 3a and 3b are reacted with electrophiles to...
The aromaticities of azines relative to benzene have been estimated by fusion with 15,16-dimethyldihydropyrene. Chemicalshift data for the azine-fused dihydropyrenes (calculated at GIAO HF/6-31G*//B3LYP/6-31 + G*) were used to estimate thereduction...
Based on the fact that the thymidine phosphorylase inhibitors are considered potential anti-tumor agents, a range of novel oxadiazole derivatives 3a–3u was designed and synthesized by a simple and facile synthetic route. The biological assay...

2,3,4,5,6-Pentasubstituted tetrahydropyrans have been prepared in good yield (42–57%) with excellent dr (>95:5) and er (>95:5) using a one-pot lithiation–borylation, allylation and Prins cyclisation reaction.
Abstract: The reactions of Hoppe’s lithiated carbamates with vinylboranes and boronic esters give allylic boranes/boronic esters, and subsequent addition of aldehydes provides a new route to enantioenriched homoallylic alcohols with high...
We have developed a process for the homologation of boranes and boronic esters using Hoppe-type lithiated carbamates which shows very broad substratescope. The Hoppe-type lithiated carbamates are effectively chiral carbenoids and are derived from...
