and 1-naphthol-based carbamates undergo the anionic ortho-Fries rearrangement to their corresponding amides. Bulky substitution at position 8 of 1-naphthol-based carbamates makes the rearrangement an exclusive reaction, even at -90 °C, un- der a variety of conditions. The amides can be efficiently reduced to the corresponding Mannichbases. A novel route to 7-((dialkylami- no)methyl)-8-hydroxy-1-naphthaldehydes
苯酚和基于 1-萘酚的氨基甲酸酯经过阴离子邻位-弗里斯重排为其相应的酰胺。1-萘酚基氨基甲酸酯在 8 位的大量取代使重排成为一种独特的反应,即使在 -90 °C 下,在各种条件下也是如此。酰胺可以有效地还原为相应的曼尼希碱。提出了一种制备 7-((二烷基氨基) 甲基)-8-羟基-1-萘醛的新途径。
