Keeping of O,O’-bis(2-benzylideneaminophenyl) phenylphosphonite in a CCl4 solution for 50 days resulted in its spontaneous rearrangement into 1,6,7-triphenyl-3,4:9,10-dibenzo-2,11-dioxa-5,8-diaza-1-phosphatricyclo[6.3.0.01,5]undeca-3,9-diene, a representative of spirophosphoranes with P–N bonds. 相似文献

The reaction of 2-(2-benzylidenamino)phenoxy-4-tert-butylbenzo-1,3,2-dioxaphosphol with ethyl mesoxalate and ethyl trifluoropyruvate resulted in the formation of tricyclic phosphoranes with the P-C and P-N bonds. The adduct emerged from the initial reaction of the PIII derivative with the activated ketone (1: 1), further underwent the transformation via the intramolecular reaction involving the benzylideniminoaryl substituent, which resulted in the formation of the cage-like phosphoranes. 相似文献

The31P-(1H) NMR spectra of bis(alkylalkoxythiophosphoryloxy)phosphonites may be utilized to determine the enantiomeric purity (p) of O-alkylalkylthiophosphonic acids with the application of the Oro equation, p= (Q – Q)/(Q + Q), where Q is the integral intensity of the d, -form, and Q is the integral intensity of the meso forms.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 10, pp. 2225–2228, October, 1989. 相似文献

The intramolecular version of nucleophilic additon of phosphites to imines was carried out for the first time taking as an example β‐aldiminoalkylphosphites, formed from chlorophosphites and β‐aldiminoalcohols [N‐(benzylidene)‐2‐aminoethanol and R‐(+)‐N‐(benzylidene)‐2‐aminobutanol‐1]. In these reactions, stereoisomeric 1,4,2‐oxazaphosphorines were obtained in good yields. R‐(+)‐N‐(benzylidene)‐2‐aminobutanol‐1 being used as a precursor, nucleophilic attack by P(III) atom on electrophilic C atom of the CN group proceeds stereospecifically with participation of only re‐face of the two possible diastereotopic faces of the imine double bond to give the epimeric at phosphorus (3R,5R)‐2‐(β‐chloroethyl)‐2‐oxo‐3‐phenyl‐5‐ethyl‐1,4,2‐oxazaphosphorines as precursors of nonracemic α‐aminophosphonic acids. © 2003 Wiley Periodicals, Inc.

It has been shown for a wide range of epoxy compounds that their interaction with triphenylphosphonium triflate occurs with a high chemoselectivity and leads to the formation of (2-hydroxypropyl)triphenylphosphonium triflates 3 substituted in the 3-position with an alkoxy, alkylcarboxyl group, or halogen, which were isolated in a high yield. Using the methodology for the disclosure of epichlorohydrin with alcohols in the presence of boron trifluoride etherate, followed by the substitution of iodine for chlorine and treatment with triphenylphosphine, 2-hydroxypropyltriphenylphosphonium iodides 4 were also obtained. The molecular and supramolecular structure of the obtained phosphonium salts was established, and their high antitumor activity was revealed in relation to duodenal adenocarcinoma. The formation of liposomal systems based on phosphonium salt 3 and L-α-phosphatidylcholine (PC) was employed for improving the bioavailability and reducing the toxicity. They were produced by the thin film rehydration method and exhibited cytotoxic properties. This rational design of phosphonium salts 3 and 4 has promising potential of new vectors for targeted delivery into mitochondria of tumor cells. 相似文献
