3-Benzylidene-4-chromanones were converted to 3-benzylchromones in HMPA at 200 °C in excellent yields. The reaction was irreversible and efficiently promoted by palladium catalysts in a remarkably shortened reaction time (3 h), compared with the existing procedure (24 h).
3-亚苄基-4-色满酮在 HMPA 中于 200 °C 转化为 3-苄基色酮,收率极佳。与现有程序(24小时)相比,该反应是不可逆的,并通过钯催化剂有效促进,反应时间显着缩短(3小时)。

Upon reaction of 1-(2-hydroxyphenyl)-3-phenylpropane-1-ones (2'-hydroxydihydrochalcones) with dimethylaminodimethoxymethane in boiling toluene, the corresponding 3-benzylchromones are obtained in excellent yields. These latter lead to 3-benzylchroman-4-ones (bomoisoflavanones) by catalytic hydrogenetion. These reactions were applied to the synthesis of (+/-)-3-benzylchroman-4-one and (+/-)-3(4-methoxybenzyl)-5,7-dimethoxychroman-4-one, (+/-)-di-O-methyldihydroeucomin.
