Synthetic Studies Toward Alloyohimbane and Louisianin D

Chen, Hung-Wei 09 June 2006 (has links)
We have developed an one-pot reaction procedure to cis-fused bicyclic glutarimides. Synthesis of (+/-)-alloyohimbane (4) and louisianin D (5) were completed.

1. Synthetic Study of Pyrrolizidine Skeleton 2. Synthetic Study Toward Tylophorine and Cryptopleurine 3. Synthetic Study of Fused Bicyclic Glutarimides

Hsu, Ru-Ting 18 January 2005 (has links)
Reaction of 3-sulfonyl acetamides with various substituted methyl acrylate derivatives furnished pyroglutamate and glutarimidess via [3+2] and [3+3] cycloaddition respectively. The results were applied to the synthesis of pyrrolizidine skeleton, tylophorine, cryptopleurine and fused bicyclic glutarimides.
