    Fa'atatauga

    1. O le mea manogi autu i le fugalaau Hawthorn, sunflower ma le lilac tofo.

    2. E fa'aaogaina e fai ma mea manogi i le lili o le vanu.

    3. E faʻaaogaina e fai ma sui i le Osmanthus fragrans.

    4. E mafai foi ona faʻaaogaina i meaʻai i aso uma ma meaʻai.

    Meatotino

    E soluble i ethanol, soluble i le ethyl ether, benzene ma isi solvents organic, soluble foi i le vai.

    Teuina

    Teuina i se nofoaga mago, paolo, fa'aalili.

    Maumau

    1. O lona kesi ma le ea e fai ai se paluga pa. Fai matatioata puipui, ofu puipui, ma totini lima.

    2. E iai i lau tapaa ma le asu.

    3. E masani lava ona i ai i suauu taua e pei o le suauu anise fetu, suauu kumini, suauu anise fetu, suauu dill, suauu akasia, ma le suauu sana.

    4. E le mautu tele i le malamalama, e faigofie ona oxidize ma suia lanu i le ea e maua ai le anisic acid.

    5. p-Methoxybenzaldehyde e mafai ona faʻaaogaina e puipuia ai diols, dithiols, amines, hydroxylamines ma diamines.

    O le puipuiga o le diol p-methoxybenzaldehyde e mafai ona faigofie ona fausia e ala i le tali a le diol ma le aldehyde e fausia ai le acetal. O le faʻaaogaina e mafai ona avea ma vailaʻau hydrochloric poʻo zinc chloride, poʻo isi metotia e pei o le iodine catalysis ma polyaniline e pei o le vaʻavaʻa Sulfuric acid catalysis, indium trichloride catalysis, bismuth nitrate catalysis, ma isi. mea fa'atupu.

    Tali ma vaega amino P-methoxybenzaldehyde e mafai ona tali atu i vaega amino e fausia ai faavae Schiff, lea e faaitiitia e NaBH4 e fausia ai amine lona lua.

    O le fa'avaeina o mea e maua mai ai le ethylene oxide p-methoxybenzaldehyde e mafai ona tali atu i le sulfur ylides e fausia ai mea e maua mai ai le ethylene oxide, ma e mafai fo'i ona tali atu i fa'aputuga o le diazonium e maua mai ai ia mea. O le tali atu i mea e maua mai i le ethylene oxide e mafai foi ona faalautele le mama e maua mai ai mama furan.

    Fa'asagaga fa'amama I lalo ole fa'ata'ita'iga ole tetrabutylammonium bromide (TBATB), e mafai e le p-methoxybenzaldehyde ona tali atu i le acid anhydride e fa'atupu ai mea fa'amama.

    I le allylation tali, ona o le malosi electron foai aafiaga o le vaega para-methoxy, tali p-methoxybenzaldehyde ma allyltrimethylsilane i lalo o le catalysis o bismuth trifluorosulfonate e maua ai le oloa diallylated .
