A series of novel 2-(1-substituted-1,11-undecylidene)-5-arylimino-△^3-1,3,4-thiadiazolines (4) were synthesized and their structure was characterized by ^1H NMR, ^13C NMR and elemental analysis. Their solubility ...
Two representative macrocyclic lactones with methoxysulfonyl side chain(5a and 5b)were synthesized employing Michael addition with acrolein and ring enlargement as the key steps,starting from potassium,α-oxocycloai...
An efficient synthesis ofα-D-GlcpNAc-(1→2)-[α-D-ManpNAc-(1→3)-]α-L-Rhap-(1→2)-α-L-Rhap-(1→3)-α-L-Rhap(1), the repeating unit of the O10 antigen from Acinetobacter baumannii was achieved via sequenti...
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...
Six new 4"-benzyloxyimino-4"-deoxyavermectin B la derivatives were synthesized from avermectin Bla by the selective protection of C-5-hydroxy group, oxidation of C-4"-hydroxy group, and deprotection followed by rea...
