Versuchsvorschrift
The sensor Zinhbo-5 can be synthesized as shown in Scheme 1, which requires a sequential construction of two benzoxazole units. The first benzoxazole unit is constructed by reaction of 2-amino-m-cresol with 2,5-bis(hexyloxy)-4-(hydroxymethyl)benzaldehyde in three steps (in 71% yield). The second benzoxazole unit is synthesized by reaction of 2-amino-4-(tert-butyl)phenol with 4-(4-methylbenzoxazolyl)-2,5-bis(hexyloxy)benzaldehyde.
