amines. It can be introduced via a dehydrogenative silylation employing an air- and moisture-stable reagent, and is appreciably more acid-stable than the related “stabase” group. BSB protection has been used in a stereoselective synthesis of amino-alcohols involving the addition of organometallic reagents to protected amino-aldehydes under “non-chelation control”.
“苯并stabase”(BSB)保护基已应用于伯脂族胺。它可以通过使用对空气和
水分稳定的试剂进行脱氢甲
硅烷基化反应引入,并且比相关的“ stabase”基团明显更耐酸。BSB保护已用于
氨基醇的立体选择性合成,涉及在“非螯合控制”下将有机
金属试剂添加到受保护的
氨基醛中。
