    Ring Selectivity in the Na/EtOH Reduction of 1-Aryl-7-methoxynaphthalenes
    摘要:
    当1-芳基-7-甲氧基萘的苯基上没有在邻位存在取代基时,Na/EtOH还原反应优先发生在A环(选择性高达100%),生成1-芳基-7-甲氧基-1,2,3,4-四氢萘。而当1-芳基部分的邻位存在取代基时,则偏向于对B环的还原(选择性高达85:15),经乙烯基醚中间体的酸催化水解后,生成相应的8-芳基-2-四氢萘酮。

  • Ring Selectivity in the Na/EtOH Reduction of 1-Aryl-7-methoxynaphthalenes

    日期:——
    Na/EtOH reduction of 1-aryl-7-methoxynaphthalenes occurred preferentially at the A-ring when no substituents were present at the ortho-positions of the aryl group (up to 100% selectivity), to afford 1-aryl-7-methoxy-1,2,3,4-tetrahydronaphthalenes. Ortho-substitution of the 1-aryl moiety favored B-ring reduction (up to 85:15 selectivity) giving rise, after acidic hydrolysis of the ­vinyl ether intermediate, to the corresponding 8-aryl-2-tetralones.

  • General Synthesis of 8-Aryl-2-tetralones

    日期:2006.6.1
    Two alternative routes are described for the synthesis of 8-aryl-2-tetralones (1). Route A starts from alpha-tetralone 3 and involves 3 or 4 steps, with the selective Na-EtOH reduction of 1-aryl-7-methoxynaphthalenes 2 being the key step. The exclusive reduction of the A ring of naphthalenes 2 occurs when the aryl group at C-1 has no substituent at the ortho positions, affording tetrahydronaphthalenes 11. Reduction of the B ring of 2 becomes the major process when the aryl fragment has two substituents at the ortho positions, affording 8-aryl-2-tetralones 1 as the major component. Route B involves 5 steps starting from 2-tetralone 5, with the key step being the Suzuki coupling with triflate 4. This approach allows the synthesis of 8-aryl-2-tetralones 1 with no substituent at the ortho positions of the aryl fragment and with naphthalene and anthracene rings at C-8.
