Unimolecular cyclizations involving C-N bond formation include intramolecular alkylations and acylations were applied for a variety of azocines, while macrocyclic O-alkylations and ketalizations are the most reliable methods for oxocine core synthesis through C-O bond formation. Other types of unimolecular cyclizations are scarce and erratic, and they usually depend on stereochemistry of the open-chain precursors and require tuning of the functional groups involved.

Core 1, the most common mucin-type O-linked core structure, is formed by the action of fSl-3 galactosyltransferase (fS3GalT), which adds galactose to form Galfi 1-3GalNAc (Fig. 2a). fS3GalT is expressed in most mammalian cells. The substrate specificity of this enzyme, like others involved in O-hnked core synthesis, is influenced by the amino acid sequences of substrate proteins and their glycosylation patterns.

For the maleimido activated core synthesis, the substitution of the resin does not have to be lower than 0.25 mmol/g. A normal substitution between 0.5 and -0.8 mmol/g will suffice the synthesis.

When D-mannosyl-L-rhamnosyl-D-galactosyl-PP-ACL is produced, the trisaccharide units rapidly polymerize to form O side-chain polysaccharide. If cell envelopes from strains unable to synthesize the core are utilized, the polysaccharide is not transferred to the core, and presumably stays attached to P-ACL. This conclusion was based on the observation that the polysaccharide could be extracted only after mild, acid hydrolysis and that a phosphate group was present at the reducing end of the polysaccharide thus obtained. In mutants defective in core synthesis, O side-chains were, indeed, found to accumulate, presumably in a form still linked to P-ACL. ...

Synthesis of tetrahydroimidazo[2,l-a]isoquinolines is another example of the reaction s utility in a fused core synthesis. Formation of compounds of structure 57 starts with 7-phenyl-5,6,7,8-tetrahydroiso-quinoline (56) amination in either DMA or tetralin in autoclave at 220 C for 18 h, which gives 53 in 41-48% yield, consecutively, although a higher yield is achieved when heating the starting material in DMA in the microwave for 12 h, which gives 58 in a 59% yield. The product is then used to construct the tetrahydroimidazo[2,l-a]isoquinoline framework using chloroacetone or 3-bromobutanone, which affords 58a,b in 46% and 75% yields, respectively...
