(Figure Presented) A new method for chiral diamine-catalyzed Robinson-type annulation was developed to construct cyclohexenone derivatives bearing a quaternary carbon stereogenic center at the 4-position in high enantiomeric excess. This method was successfully applied to the short synthesis of (+)-sporochnol A.

Sporochnols, fish deterrents from a marine alga, were synthesized, using intramolecular C-H insertion of alkylidenecarbene as a key step to construct the chiral quaternary center.
