Abstract
สารประกอบซึ่งเขียนแทนด้วยสูตร (II) เอพิเมอไรส์ด้วยปฏิกิริยาของเบสและทำให้ผลิตภัณฑ์ตกตะกอนโดยการเปลี่ยน สมดุลจะได้เอพิเมอร์ที่สัมพันธ์กันซึ่งเขียนแทนโดยสูตร (I) (สูตรเคมี) ซึ่ง Ar คือแอริลหมู่เฮเทอโรไซคลิคซึ่งเลือกถูก แทนที่ Tet คือ หมู่เททราโซลิลซึ่งเลือกถูกแทนที่ และ B1 และ B2 แต่ละตัวคือหมู่ที่ทำให้เกิดเอสเทอร์ : The compound is denoted by the formula (II) epimetry by the base reaction and precipitated by the conversion of the product. The equilibrium is obtained with a corresponding epimer denoted by the formula (I) (chemical formula), where Ar is the heterocyclic aryl group, which is selected in place of the Tet is the tetrazoline group. Which is chosen to be replaced, and each B1 and B2 is the group that makes the ester:
