An enantioselective preparation of both enantiomers of alkaloid 241D 1 and its C-4 epimer is reported. This simple and concise synthesis, seven steps from pent-3-en-2-one, involves a highly diastereoselective Mannich-type cyclisation as the key step.
报告了生物碱 241D 1 及其 C-4 对映体两种对映体的对映选择性制备方法。这种简单明了的合成方法,以戊-3-烯-2-酮为原料,经过七个步骤,以高非对映选择性的曼尼希式环化为关键步骤。
