## Abstract The title complex (+)‐**13x** has been prepared in an enantiomerically pure form. Its absolute configuration has been determined by single‐crystal X‐ray diffraction and has been correlated chemically to that of the 5, 6‐dimethylidene‐2‐norbornyl derivatives (—)‐**1**, (—)‐**2**, (—)‐**3
## Abstract The ^13^C‐labelled putative erythromycin biosynthetic intermediates, ((2__S__,3__S__,4__S__,5__R__,6__R__,7__R__)‐3,6,7‐trihydroxy‐2,4,6‐trimethyl[1‐^13^C]nonan‐5‐olide and __S__‐2‐acetylaminoethyl (2__R__,3__S__,4__S__,5__R__,6__S__,7__R__)‐3,5,6,7‐tetrahydroxy‐2,4,6‐trimethyl[1‐^13^C]
Reaction of elemental antimony with sulfur under mild hydrothermal conditions yielded different polysulfidoclusters of antimony. These were isolated as tetraphenylphosphonium salts [P(C 6 H 5 ) 4 ] 3 Sb 3 S 25 and [P(C 6 H 5 ) 4 ] 2 Sb 2 S 15 2(C 3 N 2 H 6 ) and their crystal structures were determi
