xycarbonyltriazoles are capable of undergoing ring-degenerate rearrangements (19 → 20) when a strong electron-withdrawing substituent (e.g. p-nitrophenyl or o,p-dinitrophenyl) is located at the N-1 position. Whereas the unrearranged diazomethyltriazole 19a decomposes thermally in benzene to give the cycloheptatriene 21a, the rearranged diazo compound 20b yields the norcaradiene 22b. Several methods

activity. (R)-GABOB (4) is a compound of great pharmacological importance because of its biological action as a neuromediator in the mammalian centralnervoussystem and has been shown to have a greater biological activity than its (S)-isomer." Its N-trimethyl derivative, (R)carnitin$ (h), plays a central role in the transportation of fatty acids through mitochondria1 membranes. To date, several synthetic
