3β-acetoxy-5β-androstan-17-one is a steroidal ketone derivative, specifically a derivative of androstane, a type of steroid with a cycloalkane structure. 3β-acetoxy-5β-androstan-17-one features a ketone group at the 17-position and a hydroxyl group at the 3β-position, which is acetylated, meaning it has an acetate group attached. The 5β-configuration indicates the orientation of the hydroxyl group at the 5th carbon in the steroid ring system. This chemical is significant in the field of organic chemistry, particularly in the study of steroidal compounds, which have various applications in medicine and biochemistry. It is a synthetic intermediate that can be used in the preparation of other steroidal drugs and hormones.

4820-41-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4820-41-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,2 and 0 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4820-41:
(6*4)+(5*8)+(4*2)+(3*0)+(2*4)+(1*1)=81
81 % 10 = 1
So 4820-41-1 is a valid CAS Registry Number.

A new and concise way to enamides by fluoroalkanosulfonyl fluoride mediated Beckmann rearrangement of α,β-unsaturated ketoximes

Yan, Zhaohua,Xu, Yun,Tian, Weisheng

supporting information, p. 7186 - 7189 (2015/02/02)

The reaction of α,β-unsaturated ketoximes with fluoroalkanosulfonyl fluorides in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) underwent the Beckmann rearrangement smoothly to afford the corresponding acid-sensitive enamides in moderate to excellent yields, which provides a new efficient method for the preparation of acid-sensitive enamides.

Regioselective esterification of polyhydroxylated steroids by Candida antarctica lipase B

Bertinotti, Anna,Carrea, Giacomo,Ottolina, Gianluca,Riva, Sergio

, p. 13165 - 13172 (2007/10/02)

The regioselectivity of Candida antarctica lipase B towards the acetylation of polyhydroxylated steroids has been systematically investigated. The enzyme showed a marked preference for the alcoholic moieties on the A ring and: on the steroidal side chain, making it possible the selective acylation at the positions 3 or 21 of polyhydroxy steroids. Acylation with the synthetically useful esters chloroacetate and levulinate was also accomplished, whereas esterification with benzoate and pivaloate was unsuccessful.

STEROIDS .LIII. TRANSFORMATION OF 3β-ACETOXY-5α-ANDROSTAN-17-ONE INTO 17α- AND 17β-AMINO DERIVATIVES OF 5α-ANDROSTAN-3β-OL

Nadaraia, N. Sh.,Sladkov, V. I.,Kuleshova, L. N.,Suvorov, N. N.

, p. 481 - 485 (2007/10/02)

The epimeric 17α- and 17β-amino-5α-androstan-3β-ols were synthesized from 3β-acetoxy-5α-androstan-17-one.The configurations at the C17 atom were demonstrated by the 1H NMR method.
