Oxetin (1a), a unique antibiotic having an oxetane ring, and its three stereoisomers (1b, 1c, and 1d) were synthesized from the known aldehyde (6) by utilizing a highly regio- and stereoselective epoxide ring-opening reaction. The biological activities of these oxetin stereoisomers were compared.
Oxetin(1a)是一种独特的含氧杂环的抗生素,其三种立体异构体(1b、1c和1d)是通过利用高度区域和立体选择性环氧化开环反应从已知的醛(6)合成的。对这些氧杂环立体异构体的生物活性进行了比较。
