62251-98-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 62251-98-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,2,5 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 62251-98:
(7*6)+(6*2)+(5*2)+(4*5)+(3*1)+(2*9)+(1*8)=113
113 % 10 = 3
So 62251-98-3 is a valid CAS Registry Number.

Intramolecular 1,6-conjugate addition approach for construction of the hydrindane framework: Total synthesis of (±)-coronafacic acid

Nara, Shinji,Toshima, Hiroaki,Ichihara, Akitami

, p. 6745 - 6748 (1996)

A new approach for the construction of the hydrindane framework has been achieved by intramolecular 1,6-conjugate addition under some basic conditions. The precursors, α, β, γ, δ-unsaturated esters (11a-11d) were synthesized from the ester 8 and acrolein derivatives (6a-6d) via aldol condensation. This methodology was applied to the total synthesis of (±)-coronafacic acid and its analogues.

Stereoselective Route to Functionalized cis-Hydrindanes from Tricyclo2,6>decan-10-ones. A Total Synthesis of (+/-)-Coronafacic Acid

Mehta, Goverdhan,Praveen, Marapaka

, p. 1573 - 1575 (1993)

A flexible approach to functionalized cis-hydrindanes via Haller-Bauer type cleavage of endo-tricyclo2,6>decan-10-ones is delineated and its efficacy demonstrated through a concise synthesis of (+/-)-coronafacic acid.

A scalable synthesis of (+)-coronafacic acid

Kato, Nobuki,Miyagawa, Saki,Nomoto, Haruna,Nakayama, Misuzu,Iwashita, Makoto,Ueda, Minoru

, p. 423 - 430 (2020/02/11)

A facile, efficient, and scalable synthesis of optically pure coronafacic acid by resolution of racemic coronafacic acid obtained using an improved version of Watson's method has been developed. By optimizing the boron-mediated aldol reaction of Watson, we were able to prepare 2.1 g of racemic coronafacic acid. This was coupled with (S)-4-isopropyl-2-oxazolidinone to give a mixture of diastereomeric coronafacyl oxazolidinones, which were readily separable by silica-gel column chromatography to give 630 mg of optically pure (+)-coronafacic acid.

Azido-coronatine: A useful platform for "click chemistry"- mediated probe synthesis for bioorganic studies

Okada, Masahiro,Egoshi, Syuusuke,Ueda, Minoru

, p. 2092 - 2095 (2011/06/19)

We report on the development of azide-coronatine as a useful platform for azide alkyne cycloaddition ("click chemistry")-mediated synthesis of molecular probes. (p)-Azido-coronatine was synthesized in 10 steps with 11% yield using improved synthesis of coronafacic acid, in which the highly exo-selective Diels-Alder reaction (endo:exo > 1:25) is the key step. Azido coronatine was as effective as the original coronatine in a stomatal opening assay, and was easily modified to a fluorescein isothiocyanate (FITC)-labeled probe with high yield.
