DOI: 10.1021/acs.orglett.2c03908
Abstract: We describe two new methods for the 1,2-diamination of alkenes. First, either an azidium ion (ArN═N+═NAr) undergoes 1,3-dipolar cycloaddition with an alkene to give a 1,2,3-triazolinium ion directly, or an intramolecular azide-alkene cycloaddition followed by… read more here.

DOI: 10.1021/acs.orglett.4c01411
Abstract: The complete C20 framework of brianthein W was established, featuring hydroboration/allylation, to provide the C1-C2 quaternary/tertiary stereoarray with excellent stereocontrol. Intramolecular nitrile oxide cycloaddition (INOC) was adopted as the key transformation to establish the trans-fused… read more here.

DOI: 10.1055/s-0043-1775468
Abstract: The diastereoselective synthesis of NH-unprotected pyrrolidin-2-ylidene derivatives was accomplished via 1,3-dipolar cycloaddition of H-bond-assisted azomethine ylides with chalcones. This process resulted in the formation of three stereogenic centers, exhibiting excellent diastereoselectivity. The effectiveness of this… read more here.

DOI: 10.1103/physrevlett.133.233003
Abstract: We investigate the driven-dissipative dynamics of multilevel atomic arrays interacting via dipolar interactions at subwavelength spacings. Unlike two-level atoms in the weakly excited regime, multilevel atoms can become strongly entangled. The entanglement manifests as the… read more here.
