A reliable sequence that allows for regiospecific incorporation of four alkyl substituents on an imidazole ring has been developed. This procedure involves the addition of a substituted amino alcohol to a thioamide and subsequent oxidation with PDC. Unlike many imidazole syntheses, acid-sensitive functionality is tolerated given the mild conditions.
已经开发了允许在
咪唑环上区域特异性结合四个烷基取代基的可靠序列。该程序涉及将取代的
氨基醇加入到
硫代酰胺中,随后用
PDC氧化。与许多
咪唑合成方法不同,在温和条件下可以耐受酸敏感性功能。
