Problems solved by technology
Many 6-substituted adenine compounds have been used as high-efficiency plant growth regulators, but there are few reports on the activity of 9-substituted adenine derivatives
Most of these improvements cannot improve the plant growth regulating activity of purine derivatives, and some even have adverse effects

Embodiment approach 1
[0021] Feeding according to adenine: carbonate: geranyl halide (molar ratio) 1:2.0:2.0, suspending 1 g of adenine in 10 mL of DMF, adding K 2 CO 3 2.1g, heat up to 70°C, add 3.2g of geranyl bromide dropwise, react at this temperature for 7 hours, filter with suction for 4 minutes, and distill under reduced pressure for 30 minutes to obtain a yellow oil. The crude product is passed through a column filled with alumina After chromatography, eluting with a mixture of methanol and chloroform with a volume ratio of 1:10, and distilling off the solvent, 2.3 g of compound (I) was obtained.
Embodiment approach 2
[0023] Join K 2 CO 3 2.4g, other same as Embodiment 1, to obtain 2.2g of compound (I).
Embodiment approach 3
[0025] Join K 2 CO 3 2.7g, other same as Embodiment 1, to obtain 2.4g of compound (I).

The present invention relates to a plant growth regulator and its synthesis method, belonging to the field of organic synthesis technology. In the concrete, it is relates to a N6, N9-digeranyladenine plant growth regulator and its synthesis process. Said synthesis process includes the following steps: making adenine be suspended in organic solvent DMF, its concentration is 0.7-1.5 mol / L, adding carbonate, heating to 70-90 deg.C, drop-adding geranyl halide, making reaction, filtering, reduced pressure distillation to obtain yellow oily liquid, then making the crude product be passed through the chromatographic column whose filler material is aluminium oxide to make purification so as to obtain the invented product.
Description
1. Technical field [0001] A kind of plant growth regulator and synthetic method of the present invention belong to the field of organic synthesis, specifically about N 6 , N 9 -Digeranyl adenine plant growth regulator and the technical scheme of its synthesis process. 2. Background technology [0002] Adenine derivatives have good plant growth regulating activity. Since purine is a relatively common drug intermediate, it itself and a series of heterocyclic compounds prepared from it as an intermediate have relatively good biological activities. It has been studied extensively at home and abroad for a long time. Herson et al. first synthesized isopentenyl purine in 1974, which is an effective plant growth regulator. Its principle of action is to promote cell division and the growth and development of active parts of growth. The structural formula is as follows: [0003] [0004] In 1975, Henderson et al. synthesized the following compounds and compared their plant grow...
