Technical Field

The invention belongs to the field of chemical medicine, and particularly relates to a chiral diallyl substituted compound with three continuous chiral centers, and a preparation method and application thereof.

Background

The chiral allyl structural unit is a popular structural unit which is widely synthesized and researched due to the fact that the chiral allyl structural unit has functional groups such as alkenyl and the like which are easy to be transformed and modified and chiral sites with stable allylic positions. The synthesis of the compound with a plurality of continuous chiral centers is very difficult due to more intramolecular stereo interference and larger steric hindrance effect. The synthesis of compounds with stereo diversity and continuous multiple chiral centers is a very desired method in the field of modern medical synthesis, but few reports are made at present due to the difficulty in controlling the stereoselectivity. Therefore, the synthesis method for synthesizing the compound with a plurality of continuous chiral centers in a three-dimensional diversity manner, which is efficient, universal and easy to operate, is always a hot research field in synthetic chemistry, but currently, there is a fresh report on efficient catalytic asymmetric synthesis.

Preparation of

0.2mmol of the product obtained in example 3, 29.2mg of lithium chloride, 1.5mL of DMF and 13. mu.L of water were added to a reaction tube under argon atmosphere and reacted for 2 hours under reflux. After the reaction was completed, 2.5mL of a saturated ammonium chloride solution was added, extraction was performed three times with 2.5mL of diethyl ether, and the combined organic phases were dried over anhydrous magnesium sulfate. The product was obtained in 65% yield by removing the solvent under reduced pressure and then purifying by silica gel column chromatography, diastereoselectivity by nuclear magnetic assay 1:0:0:0,¹H NMR(400MHz,Chloroform-d)δ7.87–7.77(m,3H),7.72(d,J＝1.8Hz,1H),7.51–7.45(m,4H),7.42(dd,J＝8.5,1.9Hz,1H),7.21–7.15(m,2H),6.11(dddd,J＝32.9,17.0,10.2,8.0Hz,2H),5.29(ddt,J＝10.1,2.0,0.9Hz,2H),5.17(ddt,J＝16.9,11.7,1.1Hz,2H),3.63(t,J＝8.0Hz,1H),3.51(t,J＝7.8Hz,1H),3.37(t,J＝7.7Hz,1H).¹³c NMR (101MHz, Chloroform-d) delta 138.1,137.7,137.4,136.4,133.4,132.8,132.0,130.1,128.7,127.9,127.7,127.4,126.3,126.1,125.8,121.7,119.1,118.3,118.2,49.0,48.3, 42.8; HRMS (ESI +) calculated value C₂₄H₂₁BrN⁺([M+H]⁺) 402.0852, measurement 402.0847.
