General description

The cross-cyclotrimerization of di-tert-butyl acetylenedicarboxylate, silylacetylenes and acrylamides was studied with cationic rhodium(I)/(R)-tol-binap complex as catalyst. Glycosyl azides were subjected to 1,3-dipolar cycloaddition with di-tert-butyl acetylenedicarboxylate.

Glycosyl azides provide reliable anomeric protection stable to conditions for hydrolytic removal of ester groups, for reductive opening or release of acetalic diol protection, for the introduction of ether-type protection, and for glycosylation processes. The utility of this anomeric protection

It has been established that a cationic rhodium(I)/(R)-tol-binap complex catalyzes the cross-cyclotrimerization of silylacetylenes, di-tert-butyl acetylenedicarboxylates, and acrylamides with excellent chemo-, regio-, and enantioselectivities. Unsymmetrical alkynoates can also be employed in place of di-tert-butyl acetylenedicarboxylate for this process, but with
