Featured researches published by Katsuichi Shimoji.


Tetrahedron Letters | 1983

Magnesium and zinc-catalyzed thioketalization

E. J. Corey; Katsuichi Shimoji

Abstract Reaction of a variety of ketones with ethane-1,2-dithiol to form thioketals proceeds very efficiently and under mild conditions using magnesium or zinc triflates as catalyst.


Tetrahedron Letters | 1984

Preferential formation of 8-epi-prostaglandin f2α via the corresponding endoperoxide by a biomimetic cyclization

E. J. Corey; Chuan Shih; Neng-Yang Shih; Katsuichi Shimoji

Homolytic demercuration of the 1,2-dioxolanes 14a and 14b in the presence of oxygen leads preferentially to endoperoxidee 17 (both epimers at C*) which upon reduction affords 8-epi-prostaglandin F2α and the C(15)-epimer, a result in accord with a previous mechanistic proposal.


Tetrahedron Letters | 1980

The synthesis of new aromatic prostacyclin analog

Katsuichi Shimoji; Masaki Hayashi

Abstract The new aromatic prostacyclin analog 3a and 3b were synthesized from the allylic alcohol 5 in high regio- and stereoselectivity.
