Title compounds and their acid-addition salts are physiologically acceptable or are readily converted to physiologically-acceptable counterparts by established procedures. They are pharmacologically active on the central nervous system (CNS) and are thus useful, when administered to warm-blooded animals, to induce central stimulation, to increase vigilance and to promote normal and pathologically-inhibited drive. They are also useful as analgesics and as blood-pressure-reducing agents for warm-blooded animals. These compounds are prepared, e.g., by reducing an appropriate 2-benzylazacycloheptane and are compounded into normal dosage-form medicament compositions.

3-Allyl substituted five six and seven membered lactams, are readily available in good yields and reasonable selectivity by a formal Meerwein Eschenmoser [3,3] rearrangement, using readily available methoxymethyleniminium salts and lithium alkoxides derived from allylalcohols.
