(1.2 eq) in MeOH (50 mL) and H2O (10 mL) at 0 C.
After dissolution, aryl methyl ketone (1.0 eq) was added
over a period of 10 min. The mixture was then stirred
for 3 h at 0 C. A solid product precipitated was filtered,
washed with cold MeOH, and dried to yield 60.3–
97.5%. Utilizing the same procedure, thirty-two compounds
were synthesized.
A mixture of acetyl pyridine, iodine (1.2 eq) and pyridine
60 mL was refluxed for 3 h. The solid product precipitated
was cooled to 0 C and filtered. The product
was washed with cold pyridine and dried to afford 4–6
in quantitative yield.
A mixture of 3 (R1 = a–h, R2 = a–d), dry ammonium acetate
and 4, 5, or 6 in dry MeOH was heated to 80 C for
12–24 h under nitrogen gas. The solvent was removed
by evaporation under reduced pressure, and the residue
was diluted with ethyl acetate (100 mL), washed wit
Aryl aldehyde was added to the solution of 85% KOH (1.2 eq) in MeOH (50 mL) and H2O (10 mL) at 0 C.
After dissolution, aryl methyl ketone (1.0 eq) was added over a period of 10 min. The mixture was then stirred
for 3 h at 0 C. A solid product precipitated was filtered,washed with cold MeOH, and dried to yield 60.3–
97.5%. Utilizing the same procedure, thirty-two compounds were synthesized.
将芳醛在0℃下加入85％的KOH（1.2当量）在MeOH（50mL）和H2O（10mL）的溶液中。在溶解后，在10分钟的时间内加入芳基甲基甲酮（1.0当量）。然后将该混合物在0℃下搅拌3小时。沉淀下来的固体产物经过过滤，用冷的MeOH清洗，并干燥而得到60.3－97.5％的产率。利用相同的步骤，合成了32种化合物。
