Chemical Properties

clear colorless liquid

Uses

1,2-Bis(trimethylsilyloxy)cyclobutene is a useful chemical reactant used in the preparation and biological activity of serine and threonine β-lactones as inhibitors of hepatitis A virus 3C cysteine proteinase.

General Description

Photocycloaddition of 2-cyclohexenones to 1,2-bis(trimethyl-siloxy)cyclobutene has been studied. It undergoes Aldol condensation reaction with carbonyl compounds. It reacts with Br2 to give cyclobutanedione.

Check Digit Verification of cas no

The CAS Registry Mumber 17082-61-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,0,8 and 2 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 17082-61:
(7*1)+(6*7)+(5*0)+(4*8)+(3*2)+(2*6)+(1*1)=100
100 % 10 = 0
So 17082-61-0 is a valid CAS Registry Number.

Diastereo- and Enantioselective Synthesis of (+)- and (-)-cis-2-Aminocyclobutanols

Bisel, Philippe,Breitling, Elke,Frahm, August Wilhelm

, p. 729 - 733 (1998)

The hitherto unknown (+)- and (-)-cis-2-aminocyclobutanols 6a,b and 7a,b, as well as the corresponding benzyloxycyclobutanamines 8a,b, have been synthesized by means of asymmetric reductive amination, with de values of 100percent and ee values ranging from 96.9 to 99.8percent. The relative cis configuration has been established by NO experiments, whereas the absolute stereochemistry has been deduced from the CD spectra of the corresponding salicylidene derivatives and confirms the like induction at C-1.

Convenient Preparation of 'High-Surface Sodium' in Liquid Ammonia: Use in the Acyloin Reaction

Makosza, Mieczyslaw,Grela, Karol

, p. 267 - 268 (1997)

'Sodium on solid support' (5-20 wt.% of Na on NaCl, glass powder, poly(ethylene) and poly(propylene)) can be conveniently prepared via low-temperature (-33°C) deposition of sodium from its solution in liquid ammonia. Use of this reagent in the acyloin reaction of carboxylic esters gave the corresponding products in good yields.

A convenient one-pot preparation of stable equivalents of cyclobutane-1,2-dione and cyclobutanetrione

Deguest, Geoffrey,Bischoff, Laurent,Fruit, Corinne,Marsais, Francis

, p. 841 - 847 (2008)

A very short, high-yielding, one-pot procedure has been developed for the preparation of half-protected cyclobutane-1,2-dione. This compound is much more stable than cyclobutane-1,2-dione itself and allowed further transformation to give diprotected cyclobutanetrione equivalents. Copyright Taylor & Francis Group, LLC.

Paragraph 0023; 0024; 0025; 0026; 0027; 0028-0044, (2017/10/07)

The invention belongs to the field of chemical material production, and especially relates to 1,2-bis(trimethylsilyloxy)cyclobutene, and a preparation method thereof. Preparation chemical equation of 1,2-bis(trimethylsilyloxy)cyclobutene is represented by a formula in the invention. According to the preparation method, existing of unreacted metallic sodium residue in a reaction mixture is indicated based on a phenomenon that a blue compound is obtained via reaction of benzophenone with metallic sodium in an anhydrous solution; and a convenient and feasible method used for determining metallic sodium residual after reaction is provided, and potential safety hazards in post treatment processes are avoided completely.
