139630-91-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 139630-91-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,6,3 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139630-91:
(8*1)+(7*3)+(6*9)+(5*6)+(4*3)+(3*0)+(2*9)+(1*1)=144
144 % 10 = 4
So 139630-91-4 is a valid CAS Registry Number.

Enantioselective Total Synthesis of Didesepoxyrhizoxin

Kende, Andrew S.,Blass, Benjamin E.,Henry, James R.

, p. 4741 - 4744 (1995)

The first synthesis of the antitumor macrolide didesepoxyrhizoxin is described.

Enantioselective total synthesis of the antitumor macrolide rhizoxin D

Lafontaine, Jennifer A.,Provencal, David P.,Gardelli, Cristina,Leahy, James W.

, p. 4215 - 4234 (2007/10/03)

The convergent, highly enantioselective synthesis of rhizoxin D, a natural product possessing potent antitumor and antifungal bioactivity, is described. The C(1)-C(9) fragment of the molecule was synthesized utilizing a threefold pseudosymmetric intermediate ultimately derived from γ-butyrolactone. The central core of rhizoxin D was prepared via a chiral resolution/asymmetric aldol protocol. Several methods for the generation of the polyene fragment were explored, and the side-chain was ultimately prepared from serine in six steps. The unification of the left and right wings of the molecule was achieved using a one-step olefination protocol, and the macrocyclization was carried out using a Horner-Emmons olefination at the C(2)-C(3) olefin.

Intramolecular palladium(II)-mediated alkoxy carbonylation as a route to functionalized tetrahydropyrans. synthesis of the C9-C32 segment of phorboxazole A

White, James D.,Kranemann, Christian L.,Kuntiyong, Punlop

, p. 4003 - 4006 (2007/10/03)

matrix presented Hydroxy alkene 12, synthesized stereoselectively from 2-methyloxazole-4-carboxaldehyde, underwent intramolecular methoxy carbonylation in the presence of palladium(II) acetate to give 13 in which all five stereogenic centers around the tetrahydropyran correspond to those in ring C of phorboxazole A. Aldehyde 15, derived from 13, was linked to hydroxy alkene 23 via a Wittig coupling, and the composite 25 was subjected to a second palladium(II) acetate mediated methoxy carbonylation to yield 26, accompanied by acetoxy ester 27.
