Benzeneselenenyl triflate

Y. Ito and T. Ogawa, Benzeneselenenyl triflate as a promoter of thioglycosides A new method for O-glycosylation using thioglycosides, Tetrahedron Lett. 29 1061 (1988). [Pg.376]

The same cyclization of allylic O-methylisoureas provides imidazolines or 5,6-dihydro-l,3-oxazines (when catalyzed by benzeneselenenyl triflate).3... [Pg.20]

Related to the activation of thioglycosides by sulfenylation are selenylation type reactions (E = SeR) (Scheme 4.15). Arylselenylating type promoters used with thioglycosides include benzeneselenenyl triflate [199,200] or the Wphenylselenylphtalimide-trimethylsilyltriflate [201] and Wphenylselenylphtalimide-magnesium perchlorate [202] systems. [Pg.124]

Similarly, electrophilic cyclizations of dienols and trienols, such as homogeraniol and homonerol, were earned out without addition of strong acid, using benzeneselenenyl triflate as the organoselenium reagent (equations 145 and 146). [Pg.625]
