## Abstract By using complementary and selectively acting reagents (TiCl~4~ and sulfurane **16**), azafrin, the main carotenoid in the rhizomes of __Escobedia scabrifolia__, has been shown to have the (5__R__:6__R__)โ€configuration. Reaction of azafrinaldehyde (**4**) with (Ph~3~P)~3~RhCl leads to a

**The Crystal Structure and Absolute Configuration of Mikrolin.** The crystal structure and absolute configuration of mikrolin has been determined by Xโ€ray diffraction. Crystals of mikrolin belong to space group P2~1~2~1~2~1~ with __a__ = 17.867, __b__ = 7.947, __c__ = 9.824 ร…, Z = 4. The structure
