Triisopulegylborat, also known as (1R,2S,5R)-2-isopropyl-5-methylbicyclo[3.1.0]hex-2-ene, is a chiral borane reagent used in organic chemistry. It is a derivative of the more common borane reagent, borane-tetrahydrofuran (THF) complex, and is characterized by its ability to selectively reduce carbonyl compounds to alcohols with high enantioselectivity. Triisopulegylborat is particularly useful in the synthesis of chiral alcohols, as it can provide a more efficient and selective reduction compared to other borane reagents. Its unique structure, featuring a bicyclic framework with isopropyl and methyl substituents, contributes to its enhanced selectivity and reactivity in various organic transformations.
The CAS Registry Mumber 14978-27-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,9,7 and 8 respectively; the second part has 2 digits, 2 and 7 respectively. Calculate Digit Verification of CAS Registry Number 14978-27: (7*1)+(6*4)+(5*9)+(4*7)+(3*8)+(2*2)+(1*7)=139 139 % 10 = 9 So 14978-27-9 is a valid CAS Registry Number.
