hydrogen and catalytic amounts of Pd/C induced the formation of 1,3-oxazolidines from nitriles and 1,2-amino alcohols. The subsequent reductive cleavage of the NCO bond of these heterocycles occurred under the same conditions. Thus, this methodology provides a new one-pot N-alkylation of 1,2-amino alcohols using nitriles as reagents with yields up to 98%.
在室温下,氢的存在和催化量的Pd / C导致腈和1,2-氨基醇形成1,3-恶唑烷。这些杂环的NC = O键的随后还原裂解在相同条件下发生。因此,该方法使用腈作为试剂,提供了新的一锅法1,2-氨基醇的N-烷基化反应,收率高达98%。
