Paragraph 0078; 0079, (2017/04/20)
PROBLEM TO BE SOLVED: To provide a melanin generation inhibitor and a whitening agent that are excellent in whitening effect and also excellent in safety and temporal stability. SOLUTION: The invention provides a melanin generation inhibitor containing a compound represented by formula [1] as an active ingredient, a whitening agent, as well as a melanin generation inhibiting method and a whitening method by applying such agents to the skin. (R1, R2, R4, and R5 are each independently H, a hydroxyl group, an alkyl group of C1-4, or -O-C(=O)R6; R6 is an alkyl group of C1-4; R3 is H, an alkyl group of C1-4, or -C(=O)R7; and R7 is an alkyl group of C1-8.)

Acetylconiferyl aldehyde is obtained from acetylvanillin by a Wittig reaction under phase-transfer conditions; basic hydrolysis gives coniferyl aldehyde, or after reduction with sodium borohydride affords coniferyl alcohol. This method is extended to the sinapyl and coumaryl series.
