CF3CHN2 in CH3CN is realized. This method shows excellent generality, affording a wide range of trifluoromethyl-substituted cyclopropanes bearing azlactone rings in good to high yields and diastereoselectivities. With the products in hand, the trifluoromethyl-substituted cyclopropane α-amino acids and relative peptide derivatives could be readily obtained.
实现了用CF 3 CHN 2在CH 3 CN中的储备溶液对三取代的烯烃氮杂内酯进行简便的热力学环丙烷化。该方法显示出优异的通用性,可提供多种具有氮杂内酯环的三氟甲基取代的环丙烷,并具有良好或高产率和非对映选择性。手持产品,可以容易地获得三氟甲基取代的环丙烷α-氨基酸和相关的肽衍生物。
