Synthesis and X-Ray Crystal Structure of K 4 PbTe 3 •2(en). -The single crystal XRD of (III) (space group P1, Z = 2) shows a structure similar to Pb 2 Te 2-3 , but with one of the Pb atoms absent. The trigonal pyramidal PbTe 4-3 anions and four of the five crystallographically distinct K atoms form
## Abstract magnified image A series of chiral, nonracemic oxadiazines have been prepared from (1__R__,2__S__)‐ephedrine, (1__R__,2__S__)‐norephedrine, and L‐phenylalaninol. The synthesis of the __Ephedra__‐based oxadiazines was accomplished by a process of __N__‐nitrosation, reduction, acylation,
