calix[4]resorcinol core with four branches each containing multiple 1,2,3-triazole units have been synthesized in one-step by acid catalyzed condensation of resorcinols with a new aldehyde dendron, namely, 4-3,5-bis[(1-benzyl-1H-1,2,3-triazol-4-yl)- methoxy]benzyloxy}benzaldehyde (obtained by alkyne–azide cycloaddition). The reaction proceeds stereoselectively to form rccc-diastereoisomers in high yields
通过酸催化间苯二酚与新的醛树状体(即 4- 3,5-bis[(1-benzyl-1 H -1,2,3-triazol-4-yl)-methoxy]benzyloxy}苯甲醛(通过炔烃-叠氮化物环加成获得)。该反应以立体选择性进行,以高产率形成rccc -非对映异构体。
