With the volume and accessibility of scientific research increasing across the world, it has never been more important to continue building the reputation for quality and ethical publishing we’ve spent the past two centuries establishing. 125995-03-1, Name is Atorvastatin lactone, molecular formula is C33H33FN2O4. In a Patent,once mentioned of 125995-03-1, name: Atorvastatin lactone
There is provided a process for the preparation of a compound of formula (7) or salts thereof: wherein R1 represents a hydrogen or a hydrocarbyl group, R2 represents a hydrogen or substituent group, R3 represents a hydrogen or a hydrocarbyl group, and X represents a hydrogen or substituent group which comprises a) cyanating a compound of formula (1): wherein Y represents a halo group, preferably CI or Br; P1 represents hydrogen or a protecting group, and W represents =0 or -OP2, in which P2 represents hydrogen or a protecting group, to give a compound of formula (2): b) reducing the compound of formula (2) to give a compound of formula (3): coupling the compound of formula (3) with a compound of formula (4): to give a compound of formula (5): when W represents -OP2, deprotecting and then oxidising the compound of formula (5) to give a compound of formula (6): and e) subjecting the compound of formula (5) when W represents =O, or compound of formula (6) to ring-opening, and removal of any remaining protecting groups, to give a compound of formula (7) or salts thereof.
The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 125995-03-1 is helpful to your research., name: Atorvastatin lactone
