Two efficient phase-transfer-catalyzed protocols for the diastereoselective synthesis of cis and trans isomers of 2,6-diaryltetrahydrothiopyran-4-ones (2,6-DATHTPs) have been developed. In a study of the scope of the reactions, differently substituted 2,6-DATHTPs were successfully accessed in high yields and diastereomeric excessses on both experimental and preparative scales.
已经开发了两种有效的相转移催化方案,用于非对映选择性合成 2,6-二芳基四氢噻喃-4-酮 (2,6-DATHTPs) 的顺式和反式异构体。在对反应范围的研究中,不同取代的 2,6-DATHTP 在实验和制备规模上均以高产率和非对映体过量成功获得。
