The doubly Lewis-acid functionalised aniline PhN[(CH2)3B(C6F5)2]2 features two competing boron functions in fast exchange for binding to the central Lewis base. It shows catalytic activity typical for FLPs in H/D-scrambling and catalytic hydrogenation experiments. By contrast, the singly acid-functionalised PhMeN(CH2)3B(C6F5)2 reveals a dramatically smaller catalytic activity in analogous experiments.

Three novel phosphine-free Ru-alkylidenes (7a-7c) have been synthesized and utilized as efficient catalysts for ring closing metathesis (RCM) reaction. Spectroscopic data, i.e. NMR and HRMS, along with single crystal X-ray diffraction analysis, were used
RED FLUORESCENT PROBE FOR USE IN DETECTION OF PEPTIDASE ACTIVITY

Paragraph 0086; 0088, (2020/03/28)
[Problem] A problem addressed by the present invention is to provide a novel fluorescent probe having excellent tissue permeability that is capable of detecting the peptidase activity expressed at a high level in cancer cells and the like as a response of long-wavelength red fluorescence. [Solution] A compound represented by formula (I) or a salt thereof: [In the formula, A represents a ring structure selected from the group consisting of a thiophene ring, a cyclopentene ring, a cyclopentadiene ring, and a furan ring; X represents a C0-C3 alkylene group;Y represents O, S, C(═O)O, or NH,Z represents O, C(Ra) (Rb), Si(Ra) (Rb), Ge(Ra) (Rb), Sn(Ra) (Rb), Se, P(Rc), or P(Rc) (═O) (where Ra and Rb each independently represent a hydrogen atom or an alkyl group, and Rc represents a hydrogen atom, an alkyl group, or an aryl group);R1 and R2 each independently represent from one to three of the same or different substituents selected from the group consisting of a hydrogen atom, a hydroxyl group, a halogen atom, and an alkyl group, a sulfo group, a carboxyl group, an ester group, an amide group, and an azide group each of which may be substituted;R3 represents an acyl residue derived from an amino acid (where the acyl residue is a residue obtained by removing an OH group from a carboxyl group of the amino acid);R4 and R5 each independently represent a hydrogen atom or an alkyl group (where when R4 or R5 is an alkyl group, the R4 or R5, together with R2, may form a ring structure comprising a nitrogen atom to which R4 and R5 are bonded).]
