Synthesis method of oxygen-containing derivative bark beetle pheromone verbena ketene of alpha-pinene and verbenol

Abstract

The invention provides a synthesis method of an oxygen-containing derivative bark beetle pheromone verbena ketene of alpha-pinene and verbenol, which is a synthesis method of the verbena ketene and the verbenol with high conversion rate, wherein the conversion rate of the alpha-pinene is nearly 100 percent; the yield of (-) -verbena ketene is 57 percent, the yield of (+)-verbena ketene is 60 percent, the yield of (-)-cis verbenol is 89 percent, the yield of (+)-cis verbenol is 79 percent, the yield of (-) -trans verbenol is 51 percent, and the yield of (+)-trans verbenol is 49 percent. The obtained products oxygen-containing derivative bark beetle pheromone verbena ketene of alpha-pinene and verbenol can be used for preventing pinaceae plant pests.

Description

technical field

[0001] The invention belongs to a method for synthesizing oxygen-containing derivatives of α-pinene, and relates to a method for synthesizing the oxygen-containing derivatives of α-pinene, the beetle pheromone verbenone and verbenol. Background technique

[0002] Tomicus piniperda L is the main pest of pinaceae and one of the common forest pests in the world. In foreign countries, the insect mainly harms the European red pine Pinus sylverstris, the coastal pine P.pinaster, the European black pine P.nigra and the red pine P.densiflora and other pine trees. In China, P. yunnanensis, P. massolangbianensis and P. densata are mainly harmful to P. yunnanensis. At the end of the 1970s, the vertical pit cut-tip beetle occurred on a large scale in Yunnan, resulting in the death of a large area of ​​Yunnan pine. In recent years, the pest has been seriously harmful in Northeast my country, causing huge losses to forestry production and ecological environment construct...
