This paper reports the stereoselective synthesis of a novel nucleoside, 4'-methyl branched and bicyclo [3.1.0] hexane locked-nucleoside 12, using a sequential [3,3]-sigmatropic rearrangement/carbene cycloaddition reaction/Curtius reaction strategy with a high stereoselectivity.

Azido contained polymers were treated with various substituted N-propargyl tetrazoles in $CH_2Cl_2/H_2O$ at room temperature by Cu-catalyzed [2+3] cycloaddition to afford high yields of the corresponding polymers, possessing both triazole and tetrazole moiety.

Bromo-acivicin derivative(17) and its homologs(15,16,8) were synthesized by 1,3-dipolar cycloaddition of vinyl glycine derivative(13) and allylglycine derivatives(9,12), respectively, with bromonitrile oxide(5).

Heating [Cp＊Rh(η²-NO₃)(OTf) (1) and PhC≡CPh in EtOH for 3 h gave a η⁴-cyclobutadienerhodium complex, [Cp＊Rh(η⁴-C₄Ph₄)] (2). Complex 1 reacted with HC=CPh in acetone at room temperature for 3 h to give a (η⁴-cyclobutadiene)-rhodium complex, [Cp＊Rh(η⁴-C₄HPhC=CPh)] (3). Whereas, the reactions of 1 with HC=CCH₂Cl in acetone at room temperature for 3 h gave the triply halide-bridged dinuclear rhodium complex, [Cp＊Rh(μ₂-Cl)₃RhCp＊](OTf) (4). Complexes 2-4 have been structurally characterized by X-ray diffraction.

Oxypalmatine and oxypseudopalmatine were synthesized in three steps from the benzonitrile 11 and toluamides 12a, b. The lithiated cycloaddition reaction yielded 3-arylisoquinolinone intermediates. A subsequent internal SN2 reaction produced the corresponding 8-oxoprotoberberines, oxypalmatine and oxypseudopalmatine.
