  Synthesis and herbicidal activity of substituted tetrahydronaphthalenes: I

  摘要：

  AbstractThis paper reports the synthesis and the biological activity of substituted 6‐alkyl‐1,2,3,4‐tetrahydro‐1,1‐dimethylnaphthalenes in which the substituents at the 5‐ and/or 7‐position are varied with a multitide of functional groups. These compounds exhibited pre‐emergent herbicidal activity which was a function of the electron‐withdrawing ability and the size of the groups substituted at the 5‐ and/or 7‐position. Nitro and/or nitrile groups at these positions tended to optimize activity.

• Selective syntheses of substituted 6-alkyl-1,1-dimethyl-1,2,3,4-tetrahydronaphthalenes

  日期：1993.3

  Beta-ionone is cyclized to 1,1,6-trimethyl-1,2,3,4-tetrahydronaphthalene in 80-95% yield. Selective derivatization at the 5- and/or 7-positions of 6-alkyl-1,1-dimethyl-1,2,3,4-tetrahydronaphthalenes was achieved by nitration, acylation, and reduction.
