A flexible two-step asymmetric approach to N-protected (R)-5-alkyl tetramates and (R)-5-alkyl tetramic acid derivatives is described. The method is based on the diastereoselective alkylation of (R)-phenylglycinol derived tetramates 7 and 8, which are the first synthetic equivalents to chiral nonracemic tetramate 5-carbanionic synthons A.

【期刊论文】A versatile approach for the asymmetric synthesis of 3-alkyl-2,3-dihydro-1H-isoindolin-1-ones

Based on the use of (R)-p-benzyloxyphenylglycinol (10) as a new oxidatively cleavable chiral auxiliary, a flexible approach to (R)-3-alkyl-2,3-dihydro-1H-isoindolin-1-ones via a diastereoselective reductive-alkylation is developed. The oxidative cleavage of the chiral auxiliary by CAN under mild conditions ensured the access to (R)-3-alkyl-2,3-dihydro-1H-isoindolin-1-ones with ee at least 92%.
