Syntheses of Bridged Bisquinonemethides with Double Acylketeneaminal Structure Starting with 1 , the synthesis of bis( tert ‐butyl)ester 2 is described. Some reactions including methylation of 2 to give 3 and 4 , ( 4 → 5 ) and deprotonation of 5 to 6 are reported. Possible structures of deprotonation products are discussed, based on NMR results.
