## Abstract A route to optically active variously substituted 4‐methyl‐ and 4‐methyl‐7‐substituted 1,3,4,5‐tetrahydro‐2__H__‐1,5‐benzo‐diazepin‐2‐ones as analogues of commercially available Lofendazam (7‐chloro‐5‐phenyl‐1,3,4,5‐tetrahydro‐2__H__‐1,5‐benzodiazepin‐2‐one, 1) was developed. Fortyone v
The reaction of PTAD with 2-trimethylsilyl-, 2-chloro-, 2-cyano-, and 2-methoxycarbonylnorbornadienes 1 ad, respectively, was investigated. In all cases homo Diels-Alder adducts were obtained, for 1 a the unexpected regioisomer, the 1-trimethylsilyl derivative 2a, and for other norbornadienes 1 b-d
