118893-61-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 118893-61-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,8,9 and 3 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 118893-61:
161 % 10 = 1
So 118893-61-1 is a valid CAS Registry Number.

Synthetic efforts toward the macrolactone core of leucascandrolide A

Ferrie, Laurent,Boulard, Lucie,Pradaux, Fabienne,Bouzbouz, Samir,Reymond, Sebastien,Capdevielle, Patrice,Cossy, Janine

, p. 1864 - 1880 (2008/09/18)

(Chemical Equation Presented) A chemoselective synthesis of 1, the macrocyclic core of leucascandrolide A, has been achieved by utilizing highly enantioselective allylmetalations, an enantioselective Noyori reduction of a propargylic ketone, and olefin metatheses as the key steps.

Synthesis of leucascandrolide A via a spontaneous macrolactolization

Wang, Ying,Janjic, Jelena,Kozmin, Sergey A.

, p. 13670 - 13671 (2007/10/03)

We have developed a concise, convergent, and stereocontrolled synthesis of (±)-leucascandrolide A (18 steps from commercially available precursors), featuring a complete relay of the initial stereochemical information via a series of diastereoselective transformations. Spontaneous macrolactolization discovered during this synthetic exercise has provided unprecedented access to this macrolide and demonstrated the possibility of accessing even large-ring systems in a highly controlled and efficient manner.
