A simple asymmetric access to 3-alkyl-isoindolin-1-ones was investigated through the diastereoselective alkylation of 2-[(1R)-2-hydroxy-1-phenylethyl]-2,3-dihydro-1H-isoindolin-1-one 5. High diastereoselectivities were observed with LDA or LiHMDS while the isolated yields were modest (about 50%). In contrast the use of NaHMDS gave good isolated yields (up to 85%) but lowered diastereoselectivities
通过2-[((R 1 )-2-羟基-1-苯基乙基] -2,3-二氢-1 H -isoindolin-1的非对映选择性烷基化研究了一个简单的不对称进入3-烷基-isoindolin-1- one的方法。 -一5。用LDA或LiHMDS观察到高非对映选择性,而分离的产率中等(约50%)。相比之下,使用NaHMDS可获得良好的分离产率(高达85%),但降低了非对映选择性。该方法提供了3-烷基化的异吲哚啉-1-酮的有效不对称合成。
