The structure (including absolute stereochemistry) of olguine, an unsaturated lactone isolated from an unclassified Hyptis species, has been established by spectroscopic and X-ray analysis. Quite a few species of the Hyptis genus have been studiedl. Among the components already reported are a hypto

The structure (including absolute stereochemistry) of anamarine, a new unsaturated lactone isolated from an unclassified Hyptis species, has been established.
A hypervalent arsorane with an As-Fe bond [6: Rf 2 As\*FeCp(CO) 2 (Rf: o-C 6 H 4 C(CF 3 ) 2 O-)] was synthesized by the reaction of the arsoranide anion (4-Et 4 N: Rf 2 As\* -Et 4 N โซืโฌ ) with CpFe(CO) 2 I (5) in the presence of AgBF 4 .
