Speedy and Regioselective 1,2-Reduction of Conjugated α,β-Unsaturated Aldehydes and Ketones Using NaBH4/I2
摘要:
Synthesis of allylic alcohols from alpha,beta-unsaturated aldehydes/ketones has been achieved in excellent yields utilizing NaBH4 and iodine. This reducing agent is mild and tolerant to a number of functional groups.
Reactivity of TEMPO anion as a nucleophile and its applications for selective transformations of haloalkanes or acyl halides to aldehydes
摘要:
Sodium 2,2,6,6-tetramethylpiperidine-N-oxide (TEMPO-Na+), generated by reduction of TEMPO. with sodium naphthalenide in THF, reacted with alkyl halides or acyl halides to produce O-alkylated or acylated TEMPOs, which were in turn oxidized with mCPBA or reduced with DIBAL-H to afford the corresponding aldehydes, thus accomplishing a new protocol for the halides-carbonyls conversion.
