The scheme initially involves acylation of thiophene using a carboxylic acid to afford the acyl thiophene . 这条路线是先用羧酸使噻吩已酰化制得酸基噻吩。
Thiophene, a highly common substance, serves as a versatile precursor to a variety of amino acids . 噻吩是一种很普通的物质,它可以作为合成各种氨基酸的母体。
The predominance of these series is replaced in turn by benzothiophenes and increasingly complex ring-like compounds in the higher temperature ranges . 在更高的温度范围内,这些化合物的绝大部分又被苯噻吩和更复杂的环状化合物置换。
