Hydrogenation was only the beginning: Hantzsch esters have now been used to transfer alkyl groups to imines under mild catalytic conditions to provide a variety of amines (see scheme). Benzyl, secondary alkyl, and tertiary alkyl groups containing ether, ester, and hydroxy functionalities were transferred successfully. The use of Hantzsch esters as alkylation reagents offers a practical and complementary
氢化仅仅是个开始:汉茨酯已被用于在温和的催化条件下将烷基转移到亚胺上,以提供多种胺(参见方案)。含有醚,酯和羟基官能团的苄基,仲烷基和叔烷基已成功转移。Hantzsch酯作为烷基化试剂的使用为有机金属工艺提供了一种实用且互补的替代方法。
