Abstract: 1-Ethynyl-6,18-endo-ethenodihydrothebainehydroquinone reacted with azides in the presence of CuSO4ยท5H2O and sodium ascorbate in DMF, forming the respective 1-(N-alkyl(arylalkyl)triazol-4-yl)-6,18-endo-ethenodihydrothebainehydroquinones, which underwent retrodiene cleavage upon heating in DMF, forming functionalized tetrahydrofuro[4,3,2-fg][3]benzazocines containing naphthohydroquinone and 1,2,3-triazolyl substituents. read more here.

DOI: 10.1055/s-0036-1591958
Abstract: The attachment of N -methyliminodiacetyl boron (MIDA boron) to alkenes leads to a new type of activated alkenes. Synthetic manipulation of the alkene double bond while retaining the boron moiety offers an unprecedented opportunity for… read more here.
