23. All of the 2,n-disubstituted cyclic ethers were obtained as a mixture of dl and meso isomers (ca. 1:1).
24. 6 (3.6 mg, 0.010 mmol) and the mixture was stirred at the temperature cited in Table 2 for 0.5-8 h. After excluding the solvent to the volume of ca. 0.5 mL under reduced pressure, the obtained mixture was purified by column chromatography (hexane-EtOAc) using silica gel to give a pure cyclic ether.

26. 6 (10.3 mg, 0.030 mmol) and the mixture was stirred at the temperature cited in Table 3 for 1-2 h. The following procedure is the same as in ref. 10.
