38612-13-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 38612-13-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,6,1 and 2 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 38612-13:
(7*3)+(6*8)+(5*6)+(4*1)+(3*2)+(2*1)+(1*3)=114
114 % 10 = 4
So 38612-13-4 is a valid CAS Registry Number.

Catalytic conversion of ketones to esters: Via C(O)-C bond cleavage under transition-metal free conditions

Subaramanian, Murugan,Ramar, Palmurukan M.,Rana, Jagannath,Gupta, Virendra Kumar,Balaraman, Ekambaram

supporting information, p. 8143 - 8146 (2020/09/09)

The catalytic conversion of ketones to esters via C(O)-C bond cleavage under transition-metal free conditions is reported. This catalytic process proceeds under solvent-free conditions and offers an easy operational procedure, broad substrate scope with excellent selectivity, and reaction scalability. This journal is

Cesium Carbonate Catalyzed Esterification of N-Benzyl- N-Boc-amides under Ambient Conditions

Ye, Danfeng,Liu, Zhiyuan,Chen, Hao,Sessler, Jonathan L.,Lei, Chuanhu

supporting information, p. 6888 - 6892 (2019/09/07)

We report a general activated amide to ester transformation catalyzed by Cs2CO3. Using this approach, esterification proceeds under relatively mild conditions and without the need for a transition metal catalyst. This method exhibits broad substrate scope and represents a practical alternative to existing esterification strategies. The synthetic utility of this protocol is demonstrated via the facile synthesis of crown ether derivatives and the late-stage modification of a representative natural product and several sugars in reasonable yields.

Copper-catalyzed cross-coupling of thiols, alcohols, and oxygen for the synthesis of esters

Lim, Seungyeon,Ji, Miran,Wang, Xi,Lee, Chan,Jang, Hye-Young

supporting information, p. 591 - 595 (2015/01/30)

Copper-catalyzed, one-pot, three-component coupling reactions using thiols, alcohols, and oxygen to form a variety of esters in good yields were studied. In the presence of easily oxidized benzylic and allylic alcohols, thiols were selectively oxidized to form thionoesters, which underwent facile S/O exchange to afford esters. Thiols may be used as an alternative benzoyl source under mild aerobic conditions.
