- Functionalization of the naturally occurring linalool and nerol by the palladium catalyzed oxidation of their trisubstituted olefinic bonds
-
Linalool and nerol, bio-renewable terpenic alkenyl alcohols found in many essential oils, were selectively oxidized by molecular oxygen in the presence of the chloride-free Pd(OAc)2/p-benzoquinone catalytic system. An efficient dioxygen-coupled

- Odoriferous cyclic ethers via co-halogenation reaction: Facile preparation of nerol oxide, Florol, Florol methyl ether, and Pityol methyl ether
-
A series of odoriferous cyclic ethers, including nerol oxide (1), Floral (2), Floral methyl ether (3), and Pityol methyl ether (4b), were prepared by a versatile synthetic protocol based on co-halogenation with 1,3-dibromo-5,5-dimethylhydantoin (= 1,3-dibromo-5,5-dimethylimidazolidine-2,4- dione; DDH) as the key step. The methodology provides a facile access to important perfumery molecules from abundantly available monoterpene alcohols.

- Structure and the Synthesis of Novel Constituents of Yudzu Peel Oil and Their Conversion to Related Monoterpenes
-
Two novel minor components isolated from yudzu peel oil were characterized as monoterpene β-ketols, 1 and 3, by their synthesis, and they were converted to related monoterpenes, dihydroneroloxide (9) neroloxide (10) and ho-trienol (11).
