Tetrahedron Letters | 1987

Ring cleavage and reconstruction of five and six membered ring

Hiroshi Suemune; Kozo Oda; Kiyoshi Sakai

Abstract Under the acetalization conditions using BF 3 -etherate/ethylene glycol, cyclopentanones and cyclohexanones with the carbonyl function at the C 3 - or C 4 -position of the β-side chain undergo the facile ring cleavage to reconstruct the new ring.


Tetrahedron Letters | 1997

Side chain substitution reaction of 2-arylsulfinyl and 2-arylsulfonyl intermediates for 1β-methylcarbapenems

Kozo Oda; Akira Yoshida

Abstract Sulfoxide 5 and sulfone 6 derived from 1β-Methylcarbapenem 4 yielded the precursors of 1β-methylcarbapenems by MgBr 2 ·Et 2 O mediated C-2 side chain substitution reaction with functionalized mercaptans.
