• 論文の詳細を見る

• The Schmidt reaction of 1-benzyl-1-azacycloheptan-4-one afforded a mixture of 1-benzyl-1,4-diazacyclooctan-5-one (IV) and a tetrazole derivative (V). The treatment of menthone (VIII) was found to give a lactam (IX), plus a tetrazole derivative (X) as a minor product. 2-Methyl-4,5,6,7-tetrahydrobenzo[<I>b</I>]thiazol-7-one (XII) was subjected to the Schmidt reaction to give a lactam XIIIa; it did not afford a tetrazole derivative. The structures of these products were determined on the evidence of the NMR spectra.
