One new indoloditerpene,6,7-dehydropaxilline(1),one new indole-diketopiperazine,spirotryprostatin F(2),and one new 13-membered macrolide,N-demethylmelearoride A(3),as well as 8 known alkaloids(4-11),were isola...
A new macrolide glycoside, cuneataside F was isolated from the n-butanol extract of the stem of Sargentodoxa cuneata. The structure was elucidated on the basis of extensive 1D and 2D NMR as well as HRESI-MS spectrosco...

Two series of novel derivatives of imidazo[4,5-b]pyridine were synthesized. These compounds could be used as side chains of semisynthesised ketolide antibiotics. The side chains have free amine group which can attache...
Six novel 12-alkoxycarbonylmethylene-1,15-pentadecanolides (3) were synthesized from 2-nitrocyclo-dodecanone by the Michael addition with acrolein followed by ring enlargement, Nef reaction and Wittig-Homer reaction...

A novel macrolactonization method was developed using a chiral β-lactam as the template. This novel method features that the macrocyclization is simultaneously achieved while a TBS protected hydroxy group is deprotec...
The macrolide alkaloid euonine 1 with pharmacologic activity was prepared from the alkaloid wilforgine 2. Their structures were confirmed by IR, NMR, MS and optical rotation.
