Abstract
NEW MATERIAL:A Michael condensation product and an active methylene compound of formulas I and II (X is carbonyl, sulfonyl; Y is H, hydrocarbon, etc., R1 is hydrocarbon; R2W5 are H, hydrocarbon; R6,7 are H, hydrocabon, etc.).
EXAMPLE: (2R,3S)-3,4-dimehyl-5,7-dioxo-6-(3-oxocyclopentyl)-2-phenylperhydro- 1,4-oxazepin.
USE: Pharmaceuticals, pesticides and their synthetic intermediates. Raw material of synthetic perfumes.
PROCESS: The compound I is prepared by (1) reacting a compund IV (R8 is organic group) with an optically active compound V, (2) hydrolyzing the resulting compound VI (novel compound) to a carboxylic acid derivative (novel compound), (3) subjecting the carboxylic acid derivative to intramolecular cylization, and (4) reacting the resulting optically active compound II with a compound III.
