Carbocyclization by Radical Closure onto O-Trityl Oximes: Dramatic Effect of Diphenyl Diselenide
摘要:
O-Trityl oximes of 5- and 6-iodoaldehydes undergo radical cyclization to produce oximes when treated in refluxing tetrahydrofuran (THF) with Bu3SnH, 1,1'-azobis(cyclohexanecarbonitrile), i-Pr2NEt, and diphenyl diselenide (PhSeSePh).

Several epoxides and epoxy alcohols have been opened to the corresponding halohydrins by lithium halides with Amberlyst in CH3CN at room temperature : the reaction proceeds in quantitative yields with high degree of regioselectivity.
