The lithiumaluminumhydride reduction of 7-methoxychromanone oxime (I) and 7-methoxy-3-methylchromamone oxime (II) gave only the rearrangement product (the 2,3,4,5-tetrahydro-1,5-benzoxazepine derivative). 7-Methoxy-2-methylchromanone oxime (III) and 7-methoxy-2-isopropylchromanone oxime (IV) gave a mixture of the rearrangement product (secondary amine) and the normal reduction product (primary amine)
