TL;DR: A universal approach to the synthesis of juvenoid hydroprene and methoprene was developed on the basis of monoalkylation of acetoacetate by 1-acetoxy-5-bromo-3-methylpentane, the product of acidic decyclization of 4-methyltetrahydropyran.

TL;DR: In this article, the synthesis of the glycopeptides IIa-g were carried out by condensing glycoside i without prior protection with the hydrochlorides of the methyl and tert-butyl esters of optically pure aminoacids and dipeptides using the method of activated (N-hydroxysuccinimide) esters in the presence of N,N'-dicyclohexyicarbodiimide (DCC) and triethylamine (TEA) in tetrahydrofuran (THF)

TL;DR: In the absence of catalysts, sulfides or amines are not formed in the presence of catalyst or AICI products as mentioned in this paper, and are identi cied by comparison with authentic samples.

TL;DR: Ozonolysis of N-acyl-2-(1-methylbut-2-enyl)- and N-yerl- 2-(cyclopent-2enyl)anilines followed by treatment with NaBH4 afforded the corresponding 2-(2-hydroxyethyl-1methyl) and 2-(1,5-dihydroxypent 2-yl) derivatives as discussed by the authors.
