Novel application of a protecting group strategy has enabled a simple and efficient synthesis of the new tri-linked S2N2 macrocycles 12, 15, 17 and 20. This strategy involves the introduction of complementary protecting groups (R1 and R2) into the precursor macrocycle 4, which can then be manipulated to provide a synthetically versatile set of mono-N-protected S2N2 macrocylic building blocks 5, 7 and 8.
一种保护基策略的新应用使得新型三联S2N2大环12、15、17和20的合成变得简单而高效。这一策略涉及在前体大环4中引入互补的保护基(R1和R2),随后可以对其进行操作,以提供一套合成上多功能的单N保护的S2N2大环构件5、7和8。
