A process suitable for safely mass-producing, through a short step, cyclic compounds useful in medicines, agricultural chemicals, foods, cosmetics, and chemical products or as intermediates therefor. The process, which is for producing a compound represented by the formula:
1
{wherein Z represents an electron-attracting group; W represents optionally substituted ethylene or optionally substituted vinylene; R
3
represents hydrogen or an optionally substituted hydrocarbon group; and X represents a divalent group [provided that when W represents optionally substituted vinylene, then —X—CH
2
—Z is not —X
1
—X
2
—CH
2
—Z (wherein X
1
represents sulfur or optionally substituted nitrogen and X
2
represents optionally substituted ethylene)]} or a salt thereof, is characterized by subjecting a compound represented by the formula (II) or a salt thereof:
2
(wherein the symbols have the same meanings as the above) to a ring closure reaction in a solvent containing a carbonic diester.
Catalytic Cyclophanes. Part VIII. Cytochrome P-450 activity of a porphyrin-bridged cyclophane

porphyrin-cyclophane 1 having a porphyrin attached by two straps to an apolar cyclophane binding site was prepared. Upon metallation, the ZnII and FeIII derivatives 2 and 3, respectively, were obtained in good yields. Treatment of 3 with base yielded the μ-oxo dimer 4 in which the two oxo-bridged porphyrins moieties are both capped by cyclophane binding sites. All compounds 1–4 are freely soluble in protic solvents

The invention pertains to the synthesis, isolation, and characterization of hemiaminal for selective labeling of peptides, proteins, antibodies, and organic fragments with -C(=0) CH2NH2 and derivatives with -CH2NH2 group over -C(=0) CHRNH2 group (where R≠H). The invention also pertains to the method of single-site immobilization of proteins through N-terminus Gly on solid phase. The invention includes late-stage tagging of N-terminus Gly with an affinity tag, 19F NMR probe, and a fluorophore and a method for metal-free protein purification and isolation of analytically pure proteins.
