The natural hydroxyamides, (−)-tembamide and (−)-aegeline, and the cardiac drug (−) -denopamine have been prepared in homochiral form in good overall yield (>65%) from para - methoxy or para-allyloxybenzaldehyde by synthetic sequences involving entantioselective hydrocyanation of the aldehydes. Similar chemistry has been used to prepare analogues of the bronchodilator (−)-salbutamol both in high yield
天然羟酰胺,(-)-氨甲酰胺和(-)-aegeline以及强心药(-)-地巴胺已通过对位甲氧基或对位烯丙氧基苯甲醛通过合成的手性形式以高总收率(> 65%)的方式制备涉及醛的对映选择性氢氰化的序列。已经使用相似的化学方法以高收率和良好的对映体过量来制备支气管扩张剂(-)-沙丁胺醇的类似物。
