A strategy for the synthesis of the lycopodium alkaloid dihydrolycolucine (1) has been investigated. Synthetic routes were developed based on N-acylpyridinium salt chemistry to prepare target fragments 3 and 4 that could ultimately converge to the natural product. Key reactions include IMDA cycloadditions and retro-Mannich ring-openings to form both the AB and the EF ring fragments. The ring C ...

Occupational asthma in two women employed in the manufacture of condoms is reported. The spores of Lycopodium clavatum, used as a rubber dusting agent, were identified as the causative agent.

The 1.2L Hartmann tube minimum ignition energy test device was used to study the of stevioside/lycopodium under different conditions, and microscopic morphology thermal stability dust before after combustion were explored. results show that: (1) gradually decreases with increase drying time, delay time mass; (2) With particle size, decreases, size reaches lowest value at 300 mesh; (3) In proces...
