Flow thermolysis rearrangements in the indole alkaloid series: 1,2-dehydroaspidospermidine
摘要:
Flow thermolysis of 1,2-dehydroaspidospermidine (1) at various temperatures allowed isolation of all four predictable rearrangement products, namely indolenines 2 and 3 and indoles 4 and 5. The structures of the rearranged products were confirmed by chemical and spectroscopic means, particularly HMBC and HMQC NMR techniques.
