Terpenoids, including menthol, exhibit potent abilities as plant defense potentiators in agriculture and horticulture. In the current study, we developed new terpene derivatives that consisted of menthol and various amino acids and that were expected

Plants respond to herbivory by perceiving herbivore danger signal(s) (HDS(s)), including “elicitors”, that are present in herbivores’ oral secretions (OS) and act to induce defense responses. However, little is known about HDS-specific molecule

Highly diastereoselective glycosylation reactions have been developed; however, not all glycosylation reactions are diastereoselective and these reactions have probably not been reported. For some fucosylation reactions, unusually low or abnormally o

Hexopyranoside diols, mainly 4,6-diols with α- gluco , β- gluco , α- galacto , β- galacto , and α- manno configurations could be converted effectively (40 – 74% yields), to the corresponding pyruvate acetals by the coupling of the O -trialkyls

The title compound containing dihydroceramide as a ligand for CD1d was accomplished using the mannosyl, glucosaminyl, and fucosyl donors, and a sphinganine analogue, as suitable building blocks. The 2-O-unprotected mannosyl donor was coupled effectiv

A new method of ketosidation was developed using 4,5:7,8-di-O-isopropylidenated 3-deoxy-D-manno-2-octulose and its 1-O-protected derivatives as ketosyl donors in the presence of pyridinium p-toluenesulfonate to afford the α-ketoside exclusively.
