CYCLOADDITION REACTIONS OF XANTHINIUM N(7)-YLIDES WITH TRANS OLEFINIC DIPOLAROPHILES

Hori, Mikio,Kataoka, Tadashi,Shimizu, Hiroshi,Imai, Eiji,Matsumoto, Yukiharu,et al.

, p. 2199 - 2202 (2007/10/02)

The xanthinium N(7)-ylides reacted with olefinic dipolarophiles to give tetrahydropyrroloxanthine derivatives.Reaction with dimethyl fumarate gave the mixture of endo and exo adducts.The stereochemistry of these products was elucidated by 1H-NMR and X-ray analysis.Reaction with other trans olefins afforded solely endo-syn type addition products in excellent yields.
