69940-04-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 69940-04-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,9,4 and 0 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 69940-04:
(7*6)+(6*9)+(5*9)+(4*4)+(3*0)+(2*0)+(1*4)=161
161 % 10 = 1
So 69940-04-1 is a valid CAS Registry Number.

Synthesis of (+)-altholactone, (+)-7-epi-altholactone, (?)-etharvensin, and (+)-alumheptolide-A using Pd-catalyzed carbonylation

Miyazawa, Yuki,Hattori, Yasunao,Makabe, Hidefumi

, p. 4024 - 4027 (2018/10/05)

Syntheses of (+)-altholactone isolated from Goniothalamus giganteus and its C-7 epimer (+)-7-epi-altholactone, (?)-etharvensin and (+)-alumheptolide-A were achieved. The lactone ring of these compounds was constructed using Pd-catalyzed carbonylation.

Ultrasound-assisted selective deprotection of terminal acetonides catalyzed by silica-supported boron trifluoride

Xiong, Junlong,Yan, Shiqiang,Ding, Ning,Zhang, Wei,Li, Yingxia

, p. 184 - 192 (2013/07/27)

An efficient and convenient method for the selective cleavage of terminal acetonides is described. Treatment of terminal acetonides in the presence of a wide range of functional groups with silica-supported boron trifluoride as a catalyst furnished the corresponding diols in 82-95% yield under ultrasound irradiation conditions. The acid-labile p-methoxybenzyl group as a protecting group remained intact under the conditions employed to the present deprotection condition. Copyright Taylor & Francis Group, LLC.

Total synthesis of macrosphelide M from diacetone glucose

Sharma, Gangavaram V. M.,Reddy, Post Sai

experimental part, p. 2414 - 2421 (2012/05/20)

The total synthesis of macrosphelide M is described. The key steps include the preparation of the acid and alcohol fragments from diacetone glucose and (S)-malic acid, respectively, followed by Yamaguchi esterification and macrocyclization of the tris-olefin by ring-closing metathesis. Finally, one-pot deprotection of the PMB and TBS groups with TiCl4 results in the target. The C-3/C-4 stereocenters of diacetone glucose are used for the introduction of four stereocenters, whereas the fifth stereocenter is realized from (S)-malic acid. The total synthesis of macrosphelide M was achieved from diacetone glucose and (S)-malic acid. The key steps include Yamaguchi esterification and macrocyclization of the tris-olefin by the second-generation Grubbs catalyst.

We present a short, enantiospecific synthesis of four hydroxylated analogues of pyrenolide D from D-glucose based on furan oxidative spirocyclisation. Georg Thieme Verlag Stuttgart.

Sulfuric acid immobilized on silica: an efficient reusable catalyst for selective hydrolysis of the terminal O-isopropylidene group of sugar derivatives

Rajput, Vishal Kumar,Roy, Bimalendu,Mukhopadhyay, Balaram

, p. 6987 - 6991 (2007/10/03)

Sulfuric acid immobilized on silica proved to be an efficient catalyst for selective hydrolysis of the terminal O-isopropylidene group of sugar derivatives. The method is very simple and economic for large-scale synthesis in which the catalyst is recovered and reused for several runs. Reactions with di-O-isopropylidene derivatives of d-glucose, d-mannose, d-fructose and l-sorbose led to the formation of the corresponding mono-O-isopropylidene derivatives in good to excellent yields.

Phosphomolybdic acid supported on silica gel: An efficient, mild and reusable catalyst for the chemoselective hydrolysis of acetonides

Carbohydrate acetonides were chemoselectively cleaved to the corresponding diols by using environmentally benign phosphomolybdic acid (H 3PMo12O40) supported on silica gel (PMA-SiO2) at ambient temperature in a

Chemoselective hydrolysis of terminal isopropylidene acetals in acetonitrile using molecular iodine as a mild and efficient catalyst

Yadav,Satyanarayana,Raghavendra,Balanarsaiah

, p. 8745 - 8748 (2007/10/03)

A simple, mild and efficient method for deprotection of acetonides in the presence of molecular iodine is described. Acid labile protecting groups such as PMB, OMe, OBn, allyl and propargyl are compatible with the reaction conditions, while TBS, TBDPS, TMS and THP ethers were unstable under the same conditions.
