However, during a synthesis of (—)-tormesol (321), a diterpene isolated from Halimium viscosum, the cyclization of the related nonenolizable / -ketoester 322 proved sluggish as only 50% conversion was observed using catalyst [Ru]-I in combination with Ti(Oi-Pr)4 (1 equiv.). The more active [Ru]-II overcame this limitation and allowed the synthesis of cycloheptene 323 in excellent yield with a low... [Pg.28]
