step the asymmetric alkylation of pseudoephedrine glycinamide (1) or pseudoephedrine sarcosinamide (2). Practical procedures for the synthesis of 1 and 2 from pseudoephedrine and glycine methyl ester or sarcosinemethyl ester, respectively, are presented. Optimum protocols for the enolization and subsequent alkylation of 1 and 2 are described. Alkylation reactions of 1 and 2 are found to be quite efficient

Furthermore, we evaluated the structure–activity relationship (SAR) for both enantiomers of naturally occurring LAT1 substrates. Analogues were tested in cis-inhibition and trans-stimulation cell assays to determine potency and uptake rate. Surprisingly, LAT1 can transport amino acid-like substrates with wide-ranging polarities including those containing ionizable substituents. Additionally, the rate of LAT1

A general protocol for the synthesis of α-amino-α- alkyl phosphonic acids in either enantiomeric form is described based on the alkylation of chiral bicyclic phosphonamides derived from (R,R)- and (S,S)-1,2-diaminocyclohexane.

The formation of the (((diisopropyloxyphosphinyl)methyl)isopropyloxyphosphinyl)methyl dianion, (iPrO)2P(O)CH−P(O)(iPrO)CH2−, is reported and its application to the synthesis of phosphonylphosphinyl (P-C-P-C-) compounds, including analogs of biologically interesting diphosphates, is presented.

formic‐acid‐mediated rearrangements of dearomatized acylphloroglucinols to access a structurally diverse group of synthetic acylphloroglucinol scaffolds (SASs). Density‐functional theory (DFT) optimized orbital and stereochemical analyses shed light on the mechanism of these rearrangements. Products were evaluated by multiplexed activity profiling (MAP), an unbiased platform which assays multiple biological readouts
