摘要: Carboxyethyl hydroxychromans (CEHCs) are natural metabolites of vitamin E (VE). Their urinary levels can serve as useful biomarkers for the nutritional assessment VE. Moreover, specific biological activities CEHCs deserve further investigation. Here, we report a concise method to build up chiral 6-hydroxychroman scaffold VE and CEHCs. The first total synthesis (S)-δ-CEHC was accomplished in 40% overall yield 97% ee using synthon derived from naturally occurring (-)-linalool.
