Ation and, accordingly, much less tendency to catheter occlusion compared with standard insulin, insulin lispro, and insulin glulisine.21,22 Conversely, Senesh and coauthors20 demonstrated over six days that all rapidacting insulin…
Nce (SID) was defined as (Na K Ca2 Mg2) (Cl lactate) mEq/L . Hyperchloraemic metabolic acidosis was defined as SID below 40 mEq/L connected with chloraemia above 108 mmol/L in…
While alkyne metathesis is not going to displace alkene metathesis as a synthetic method, it is a complementary approach that can offer advantages. Catalysts for alkyne metathesis are still under…
Inhibitors Salinosporamide A, Omuralide and Lactacystin The structurally-related γ-lactams salinosporamide A (1), omuralide (2) and lactacystin (3), of bacterial origin, inhibit proteasome activity, and so are of interest as lead…
The enantioselective oxygenation procedures, epoxidation and dihydroxylation, developed by Barry Sharpless have dominated single-enantiomer organic synthesis. Recently, several additional methods for enantioselective oxidation have been developed, based on the α-functionalization…
Although many methods have been developed for enantioselective carbon-carbon construction, not all of these are robust and scalable. A promising recent addition has been the development of protocols for the…
Arrays of Stereogenic Centers Single enantiomer synthesis is of increasing importance in pharmaceutical production. It is essential that practical and scalable procedures be developed for controlling the absolute configuration of…
Benzyl ethers are among the most commonly used protecting groups for alcohols. PMID:23554582 Usually, these are prepared using an excess of NaH and benzyl bromide. Buy1-(Aminomethyl)cyclopentanol Okan Sirkecioglu of Istanbul…
The push toward enantiomerically-purecarbocyclic intermediates has led to the development of new methods for the enantiodifferentiation of inexpensive prochiral cyclic starting materials. For instance, Robert H. Morris of the University…
In the last few years, chiral sulfoxides have become important targets in organic synthesis, and their chemistry has recently been reviewed (Org. Chem. Highlights 2004, December 24. Link). An increasing…
