Diacetone glucose architecture as a chirality template I. Crucial effects of the intramolecular oxygens upon the LiAlH4 reduction of the propargyl alcohol of 3-C-ethynyl-1,2:5,6-di-O-isopropylidene-α-D-allofuranose derivatives
摘要:
The facile as well as regio- and stereoselective reactivity of 3-C-ethynl-1,2:5,6-di-O-isopropylidene-alpha-D-allofuranose derivatives for LiAlH4 reduction into the corresponding ethenyl derivatives were investigated. The effect of oxygen atoms on the reduction is discussed by means of semi-empirical MO calculation.

of compounds, using structure-based design concepts, coupled with optimization of cellular potency, in vitro drug–target residence times, and in vivo PK properties, to identify first-in-class inhibitors that demonstrate LDH inhibition in vivo. The lead compounds, named NCATS-SM1440 (43) and NCATS-SM1441 (52), possess desirable attributes for further studying the effect of in vivo LDH inhibition.
The first general and regioselective Pd‐catalyzed cyclocarbonylation to give α‐methylene‐β‐lactones is reported. Key to the success for this process is the use of a specific sterically demanding phosphine ligand based on N‐arylated imidazole (L11) in the presence of Pd(MeCN)2Cl2 as pre‐catalyst. A variety of easily available alkynols provide under additive‐free conditions the corresponding α‐methylene‐β‐lactones
