We report the synthesis of three novel and chiral salicylic aldehyde building blocks 6−8, each in both enantiomerically pure forms. Two of these salicylic aldehydes were prepared from (+)-camphene and each bear a [2.2.1]bicycloheptyl substituent ortho to the salicylic hydroxy group. In the third case, the chiral element at the 6-position is a (1-phenylethyl) group. The synthetic sequences consisted of ortho-alkylation of para-cresol with either camphene or styrene and subsequent ortho-formylation of the product phenols. The chromatographic separation of enantiomers was accomplished through the diastereomeric imines obtained from condensation of the racemic salicylic aldehydes with (R)-phenylglyci-
