1β-Ethenyl-2β-[(Z)-1-butenyl]-3-cyclopentene, also known as (+)-multifidene, is a chiral cyclopentene derivative featuring a vinyl group at the 1β-position and a (Z)-1-butenyl group at the 2β-position. Its synthesis involves a stereoselective approach, starting from (R)-(cyclopent-2-enyl)methanol, proceeding through a cobalt-mediated radical cyclization to form a lactone intermediate, and subsequent introduction of the olefinic side chains to achieve the final structure. 1β-Ethenyl-2β-[(Z)-1-butenyl]-3-cyclopentene exhibits defined stereochemistry, specifically (3S,4S), and is notable for its role as a natural product or synthetic target in organic chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 52886-04-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,8,8 and 6 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 52886-04:
(7*5)+(6*2)+(5*8)+(4*8)+(3*6)+(2*0)+(1*4)=141
141 % 10 = 1
So 52886-04-1 is a valid CAS Registry Number.

Synthesis of (+)-Multifidene

Hemamalini, Sundarababu,Scheffold, Rolf

, p. 447 - 451 (1995)

(+)-Multifidene ((+)-1) has been synthesized starting from (R)-(cyclopent-2-enyl)methanol ((+)-2) via its chloroformate 4, Co-mediated radical cyclization reaction to the lactone (+)-6, and introduction of the olefine side chains.

A short chemoenzymatic synthesis of (+)-Multifidene and (+)-Viridiene

Lebreton, Jacques,Alphand, Veronique,Furstoss, Roland

, p. 1011 - 1014 (2007/10/03)

(+)-Multifidene 1 and (+)-Viridiene 2, the major constituents of some brown algae pheromones, were synthesized in five steps from racemic bicycloheptenone 3 via a novel microbiological Baeyer-Villiger oxidation performed using the fungi Cunninghamella echinulata.
