Abstract
Abstract The sodium hydrosulfite reduction of N-nitroso-1, 2, 3, 4-tetrahydroisoquinoline (5) does not result in the loss of nitrogen and leads to the corresponding hydrazine 6 which upon oxidation with mercuric oxide in ethanol at 62 gives the hexahydrotetrazine 7 in 39% yield. Treatment of the N-tosyl derivative of 6 with base affords 7 in nearly quanitative yield. Oxidation of 6 in 1-butanol at 95 results in the formation of a complex product mixture from ...
