Embodiment 1

[0030] Embodiment 1: preparation formula Ia compound, X=H, Y=H in the formula

[0031] The implementation steps of this embodiment are as follows:

[0032] (1) Preparation of cinnamoyl chloride:

[0033] The reaction of cinnamic acid with thionyl chloride is as follows:

[0034]

[0035] Specifically, 74g (0.5mol) of cinnamic acid, 119g (1.0mol) of thionyl chloride and 150mL of toluene were sequentially added to a 500mL three-necked flask, and 0.2mL of N,N-dimethylformamide was added dropwise under stirring conditions. Then heat up and reflux for 2h, then use the rotary evaporator sold under the trade name RE-52AA model by Shanghai Yarong Biochemical Instrument Factory Company to carry out rotary evaporation, remove toluene and excess thionyl chloride, so obtain 81.3g light yellow oily liquid, The product was determined to be cinnamoyl chloride by conventional 1HNMR method analysis, and its yield was 98% based on cinnamic acid raw material calculation.

[0036] (2) Synth...

Embodiment 2

[0040] Embodiment 2: Preparation of a compound of formula Ib, wherein X=H, Y=Cl, a compound of formula Ic, wherein X=Cl, Y=H and a compound of formula Id, wherein X=Cl, Y=Cl

[0041] The same implementation as in Example 1 was carried out, except that cinnamic acid was replaced by o-chlorocinnamic acid, p-chlorocinnamic acid and 2,4-dichlorocinnamic acid, respectively. The obtained product was analyzed by conventional 1HNMR method, and its physical properties and NMR data are listed in Table 1.

[0044]

Embodiment 3

[0045] Embodiment 3: the preparation of formula Ia compound hydrochloride of the present invention:

[0046] Weigh 4.6g (0.02mol) of the compound of formula Ia prepared in Example 1, add it into a 100mL three-necked flask, add 30mL of water, add 1.7mL (0.02mol) of concentrated hydrochloric acid (11.7mol / L) and 8mL of water dropwise under stirring to form The solution, after dripping, continued to stir for 0.5h to obtain a clear and transparent solution. Use a rotary evaporator sold under the trade name RE-52AA model by Shanghai Yarong Biochemical Instrument Factory to carry out rotary evaporation, remove water, and obtain a white solid, which was dried , to obtain 5.00g of powdery white solid, which was determined by conventional chemical titration method.

[0047] According to the same method as above, except that sulfuric acid, nitric acid or phosphoric acid are used respectively, the sulfate, nitrate and phosphate of the compound of formula I can be prepared.

Abstract

The invention relates to an application of taking a cinnamamides compound as a plant growth regulator. The plant growth regulator composition is composed of the cinnamamides compound or a salt thereof and an agriculture or forestry acceptable carrier. The compound shown as the formula I and the salt thereof are low in production and utilization costs, small in use amount and wide in utilization concentration range, and can be widely applied to various crops or plants to promote seeds to be germinated, promote rooting, increase the output, resist adversity and improve the quality and the like. The compound is used as the novel plant growth regulator and has a very good market potential and a commercial development value in the aspects of promoting the development of green agriculture in China and guaranteeing the grain safety.

Description

【Technical field】 [0001] The invention belongs to the technical field of plant growth regulators. More specifically, the present invention relates to the use of a cinnamic amide compound or a salt thereof as a plant growth regulator. 【Background technique】 [0002] With the decreasing area of ​​arable land, increasing population and frequent occurrence of natural disasters, how to obtain food crops efficiently and stably, and how to increase production on the basis of maintaining production have become a major issue. Plant growth regulators are one of the pesticides. Large categories have played an important role in increasing agricultural production and income and improving quality. [0003] At present, the commercialized plant growth regulators in my country mainly include gibberellin, ethephon, naphthalene acetic acid, indole acetic acid, 6-benzylaminopurine and DA-6 (diethylaminoethanol hexanoate citrate), etc. There are very few varieties of plant growth regulators wit...
