A new aspartam-like sweetener (FC-APM) was prepared from aspartame (APM). Due to the protective group, FC-APM is less prone to diketopiperazine formation and therefore much more stable than aspartame at higher pH values and temperatures. A relatively

A MNDO and 300-MHz 1H NMR study of some trigonal-bipyramidal (TBP) five-coördinated phosphorus (Pv) compounds is reported. It is shown by the MNDO calculations that, in the oxaphosphole Pv TBP compounds 5a-c, the electron distribution in the axial b

A 300-MHz 1H NMR variable-temperature study of the 1′-phosphorylated trigonal-bipyramidal (TBP) tetrahydropyran-2-methyl model compound 4 is reported. For this compound, in which both the equatorial and axial sites undergoing phosphorus pseudorotat
