Synthesis of novel acridino- and phenazino-18-crown-6 ligands and their optically pure dimethyl-substituted analogues for molecular recognition studies
摘要:
Novel acridino- and phenazino-18-crown-6 ligands 5 and 6 were I,prepared from acridine-4.5-diol (9) and phenazine-1,9-diol (10) with tetraethylene glycol di-p-tosylate (11) using potassium tert-butoxide as a bar in THF. New optically pure dimethyl-substituted acridino- and phenazine-18-crown-6 ligands (R,R)-7 and (R,R)-8 were also prepared by treating 9 and 10 with optically pure dimethyl-substituted tetraethylene glycol di-p-tosylate [(S,S)-18], Molecular recognition studies on these novel ligands are underway.

A series of insect juvenile hormone analogs (juvenoids) was synthesized and studied. The basic skeleton of these juvenoids contains three rings and a short aliphatic subunit and bears two or three chiral centers (depending on the appropriate structure; see 6–9). The chiral center located in the 1,2-diphenoxypropane subunit has the configuration (RS), (R) (a series), or (S) (b series). The juvenoids
