Calculate Digit Verification of CAS Registry Number 83921-04:
(7*8)+(6*3)+(5*9)+(4*2)+(3*1)+(2*0)+(1*4)=134
134 % 10 = 4

THE ENANTIOSELECTIVE BIOTRANSFORMATION OF α-TERPINEOL AND ITS ACETATE WITH THE CULTURED CELLS OF NICOTIANA TABACUM

Suga, Takayuki,Hirata, Toshifumi,Lee, Ym Sook

, p. 1595 - 1598 (2007/10/02)

In the biotransformation of the enantiomers of p-ment-1-en-8-ol (α-terpineol) and 8-acetoxy-p-ment-1-ene (α-terpinyl acetate) with the cultured suspension cells of Nicotina tabacum, it was clarified that the cultured cells effected the hydroxylation at the 6-position of (4R)-(+)-enantiomer in preference to the (4S)-(-)-enantiomer, whereas the cells did the hydrolysis of the acetoxyl group and the hydroxylation of the ethylenic linkage of (4S)-(-)-α-terpinyl acetate in preference to the (4R)-(+)-enantiomer.
