Quality Control of 4-Methoxybenzaldehyde. Published in AMER CHEMICAL SOC in WASHINGTON ,Authors: Soley, J; Taylor, SD. The CAS is 123-11-5. Through research, I have a further understanding and discovery of 4-Methoxybenzaldehyde
The synthesis of beta-hydroxy-alpha,alpha-difluorosulfona-mides was achieved by reacting difluoromethanesulfonamides with KHMDS in the presence of an aldehyde or ketone. The reaction exhibited a dramatic counterion effect with KHMDS or NaHMDS usually giving excellent yields in minutes, while lithium bases gave little or no product. Excellent yields and high diastereomeric ratios were achieved with N-alpha-benzyl-N-alpha-phenylfluorenyl (PhF)-protected chiral amino aldehydes derived from amino acids. Following deprotection, a beta-hydroxy-alpha,alpha-sulfonamide reacted under peptide coupling and Mitsunobu conditions to furnish a peptidomimetic in an excellent overall yield.
