D. Molm et al., FRAGMENTATION REACTIONS OF QUATERNIZED GAMMA-AMINO ALCOHOLS - DIASTEREOSELECTIVE SYNTHESIS OF HIGHLY FUNCTIONALIZED OXETANES AND UNSATURATED ALDEHYDES AND KETONES WITH A (Z)-C-C DOUBLE-BOND, EUROPEAN JOURNAL OF ORGANIC CHEMISTRY, (10), 1998, pp. 2185-2191
Quaternized gamma-amino alcohols 5 derived from ternary iminium salts
2 are stereospecifically converted into both unsaturated aldehydes/ket
ones 6 with a (Z)-C-C double bond in a Grob-type fragmentation and hig
hly functionalized oxetanes 7 by intramolecular substitution.
