✦ Synopsis

A convenient and practical multi-gram procedure for the connected via amides by peptide methods. Purification is either done by recrystallization or simple filtration through synthesis of second-(G2; 4a, 5a, 5d) and third-generation (G3; 6a) dendrons with orthogonally protected functional silica gel and yields the products as analytically pure materials on a several-gram scale (even for G3). The groups in the periphery (hydroxy) and at the focal point (carboxylic acid) is described. It uses the amply available dendrons' protective groups are proven to be orthogonal (500-MHz NMR) which makes them useful components first-generation dendrons with amine and carboxylic ester functions (1) and tetrahydropyranyl-protected hydroxy and (building blocks) of a future dendron construction kit for a versatile synthesis of, for example, dendronized polymers. carboxylic acid functions (2b, 3), respectively, which are

The multi-gram scale synthesis of first-and second-deprotection of the amines are shown to be strictly orthogonal processes which makes these dendrons valuable generation dendrons with Boc-and Cbz-protected amino groups in the periphery and methyl/ethyl esters at the focal building blocks for future

The ready availability of isoprene from petrochemical sources has considerably stimulated the search for isoprene derivatives which can be used as fivecarbon synthons in terpene synthesis. Many elegant isoprene homologations have
