Synthetic example 1-5
[0022]Replace resorcinol in Synthesis Example 1-3 with 126 grams of phloroglucinol. The amount of catalyst p-toluenesulfonic acid was doubled to 3 grams. The water output reaches 2 moles as the end point of the reaction. Others are the same as Synthesis Example 1-3. The product P1-5 is obtained.
[0023] Using the reactant ratio and method of Synthesis Example 1-5, just use 110 grams of hydroquinone, 110 grams of catechol, 108 grams of p-cresol, 108 grams of o-cresol, and 128.5 grams of o-chlorophenol to replace the synthetic Resorcinol in Examples 1-5. The products P1-6, P1-7, P1-8, P1-9 and P1-10 were obtained.
[0024] The appearance, yield, and some physical and chemical properties of the products P1-1 to P1-10 obtained in Synthesis Example P1-1 to Synthesis Example P1-10 are listed in Table 1. Infrared spectroscopy, mass spectrometry, 13 C-NMR analysis and element analysis determination, P1-1——P1-10 structural formula is as follows:

Synthetic example 2-19、2-20
[0032] 96.6 grams (0.14 moles) of dihydropyrrole were used to replace dihydrofuran in Synthesis Examples 2-17 and 2-18 respectively, and the apparatus and method were the same as Synthesis Examples 2-17 and 2-18. Reaction products P2-19 and P2-20 were obtained.
[0033] The yield, appearance and physicochemical properties of the product are shown in Table 2, and their structures are shown in formulas P2-1 to P2-20:

Synthetic example 3-3
[0038] 30.2 g (0.1 mol) and 8.9 g (0.22 mol) of P1-3 chloromethyl methyl ether were used to replace the corresponding reactants in Synthesis Example 3-1, and the others were completely the same as Synthesis Example 3-1. The product P3-3 is obtained.
[0039] 33.4 grams (0.1 mol) of P1-4 and P1-5 were used to replace P1-1 in Synthesis Example 3-1, and the others were completely the same as Synthesis Example 3-1 to obtain products P3-4 and P3-5.
[0040] The yield, appearance and physical and chemical properties of P3-1-P3-5 are listed in Table 3, and the product structure is shown in formula P3-1-formula P3-5.
[0041] A series of corresponding products can be obtained by replacing chloromethyl methyl ether with other chloromethyl alkyl ethers.
