Angewandte Chemie, EarlyView.Displaying strong controlled metalating power, hydrocarbon‐soluble sodium neopentyl can deprotonate challenging non‐activated arenes and alkenes, with sodiated intermediates successfully undergoing onward functionalisation reactions. By characterising key reaction intermediates, and running computational studies on models, insight has been gained on ...

Synthesis of highly substituted allenylsilanes by alkylidenation of silylketenes [PDF]
, 2005 BACKGROUND: Allenylsilanes are useful intermediates in organic synthesis. An attractive, convergent but little used approach for their synthesis is the alkylidenation of stable silylketenes.

Fluorination of some functionalized cycloalkenes through epoxidation and oxirane opening with Deoxofluor or XtalFluor-E [PDF]
, 2017 A convenient, simple synthetic method is described for the synthesis of some fluorinecontaining, highly functionalized cycloalkane derivatives. The synthetic protocol involves the stereoselective epoxidation of selected substituted cyclohexenes as model ...

Microwave Spectrum of Cyclohexene [PDF]
Bulletin of the Chemical Society of Japan, 1969 Abstract The microwave spectrum of cyclohexene has been investigated in the frequency region from 7.3 to 27 Gc/sec with a conventional Stark modulation spectrometer, and the spectrum in the ground vibrational state has been assigned.

The iso-Nazarov reaction [PDF]
, 2017 The construction of five-membered rings is essential in organic chemistry. In this context, pentannulation reactions that provide a straightforward access to cyclopentenones are of particular interest, as these structures are not only embedded in ...

Towards broad spectrum activity-based glycosidase probes: synthesis and evaluation of deoxygenated cyclophellitol aziridines [PDF]
, 2017 Activity-based protein profiling has emerged as a powerful tool for visualizing glycosidases in complex biological samples. Several configurational cyclophellitol isomers have been shown to display high selectivity as probes for glycosidases processing ...

Stereoselective synthesis of five- and six-membered carbocycles via Matteson homologation/ring closing metathesis [PDF]
, 2023 The Matteson homologation is found to be a versatile tool for the stereoselective synthesis of polyunsaturated alkyl boronic esters, which are excellent precursors for the construction of five- and six-membered carbocycles via ring-closing metathesis ...
