Pictet-Spengler reactions of m-tyramine and aldehydes produced tetrahydroisoquinolines in the presence of a catalytic amount of Ca[OCH(CF3)2]2. This reaction occurs with a variety of aryl, heteroaryl, and alkyl aldehydes, producing tetrahydroisoquinolines in high yield and with high regioselectivity. This calcium-promoted Pictet-Spengler reaction provides a mild alternative to the traditional Bronsted
在催化量的Ca [OCH(CF3)2] 2存在下,间苯胺和醛的Pictet-Spengler反应产生四氢异喹啉。该反应与各种芳基,杂芳基和烷基醛发生,以高产率和高区域选择性产生四氢异喹啉。这种钙促进的Pictet-Spengler反应提供了通常用于这些反应的传统布朗斯台德酸的温和替代品。
