Didemnins A, B, and C were efficiently prepared in a stereocontrolled manner, producing the common macrocycle and, in a separate step, introducing the substituents on the amino group of L-threonine as optically pure units. We envisaged that disconnections between L-leucine and the HIP group (2S,4S) and between L-threonine and isostatine (3S,4R,5S) would afford two units: a HIP-isostatine unit (I) and
Didemnins A、B 和 C 以立体控制的方式有效制备,产生常见的大环,并在单独的步骤中,在 L-苏氨酸的氨基上引入取代基作为光学纯单元。我们设想 L-亮氨酸和 HIP 基团 (2S,4S) 之间以及 L-苏氨酸和异司他汀 (3S,4R,5S) 之间的断开将提供两个单元:HIP-异司他汀单元 (I) 和四肽单元 (II) )
