Abstract A short and efficient enantio- and diastereoselective synthesis of different representatives from the class of dihydro-α-pyrone natural products, including both enantiomers of goniothalamin, massoia lactone, parasorbic acid, and some derivatives is presented. It is based on the application of enantiopure α-chiral allylboronic esters in allyl additions. A short and efficient enantio- and diastereoselective
摘要 提出了一种短而有效的对映异构和非对映异构选择性合成方法,该合成方法涉及二氢-α-吡喃酮天然产物类别的不同代表,包括Goniothalamin,Massiia lactone,parasorbic acid和一些衍生物的对映异构体。它基于对映体纯的α-手性烯丙基硼酸酯在烯丙基加成中的应用。 提出了一种短而有效的对映异构和非对映异构选择性合成方法,该合成方法涉及二氢-α-吡喃酮天然产物类别的不同代表,包括Goniothalamin,Massiia lactone,parasorbic acid和一些衍生物的对映异构体。它基于对映体纯的α-手性烯丙基硼酸酯在烯丙基加成中的应用。
