1	(I) Synthetic Studies Toward Polysubstituted Pyridin-2-ones (II) Total Synthesis of Deplancheine Chen, Chung-Yi 12 January 2005 (has links) A convenient method for the preparation of hydroxyl lactams via regioselective reduction of N-alkyl-3-sulfonyl glutarimides is described. The useful building block is applied to synthesize polysubstituted pyridin-2-one, tacamonine and deplancheine. pyridine-2-one [3+3] annulation deplanecheine tacamonine regioselective reducetion
2	Synthetic Studies Toward Xylopinine Chang, Jung-Kai 18 August 2005 (has links) We use stepwise [3+3] annulation to prepare the asymmetric glutarimides, and then establish a new approach to isoquinolone skeleton starting from glutarimides via regioselective nucleophilic addition and ring-closing metathesis reaction. Finally, we applied this method to the synthetic studies toward (¡Ó)-Xylopinine. isoquinolone pyridine-2-one xylopinine ring-closing metathesis [3+3] annulation
3	Synthetic Studies Toward Polysubstituted Pyridin-2-ones and Vitamin B6 Derivatives Chung, Wen-hsuan 19 August 2005 (has links) We can construct asymmetric glutarimide while using [3+3] annulation.Then we can build substituent group in C6 position after choosing regioselective addition reaction, and then apply it to synthetic studies toward polysubstituted pyridin-2-ones and Vitamin B6 derivatives. Vitamin B6 derivatives [3+3] annulation pyridine-2-one regioselective addition reaction
