日期:1996.1.1
free-radical cyclization of unsaturated ketones is a versatile synthetic procedure with broad applicability. For example, oxidation of cyclopentanone 1a with 2 equiv of Mn(OAc)(3).2H(2)O and 1 equiv of Cu(OAc)(2).H(2)O in AcOH at 80 degrees C for 1.5 h affords 75% of bicyclo[3.2.1]oct-3-en-8-one 8a and 15% of bicyclo[3.2.1]oct-2-en-8-one 9a. Bridgedbicyclicketones that cannot enolize further are isolated

SH2, allylations of various keto compounds with 2-substituted allylic sulfones or sulfides have been efficiently performed using a ternary oxidizing mixture -i.e. manganic acetate, cupric acetate and lead dioxide- in acetic acid.
SH 2,已使用三元氧化混合物(即乙酸锰,乙酸铜和二氧化铅)在乙酸中有效地进行了各种酮化合物与2-取代的烯丙基砜或硫化物的烯丙基化反应。
