Synthesis of racemic germicidin Igor P

AB - The Buchwald/Hartwig aryl amination method was used to construct a series of chiral, non-racemic N-aryl pyrrolidinones from a common pyrrolidinone precursor and the corresponding aryl bromide. The stereochemical integrity of the N-aryl lactam after cross-coupling was proven by synthesis of the racemic compounds and comparison by 1H NMR spectroscopy using Pirkle's chiral solvating agent.

T1 - Synthesis of racemic fecapentaene-12, a potent mutagen from human feces, and its regioisomer

Synthesis of racemic sesquicarene - ScienceDirect

The importance of racemic mixtures is that ordinary laboratory synthesis which generate a stereogenic center produce a racemic mixture.

T1 - Intramolecular nitrile oxide cycloaddition (INOC) reactions in the indole series. 2. Total synthesis of racemic and optically active paliclavine and 5-epi-paliclavine

N2 - The Buchwald/Hartwig aryl amination method was used to construct a series of chiral, non-racemic N-aryl pyrrolidinones from a common pyrrolidinone precursor and the corresponding aryl bromide. The stereochemical integrity of the N-aryl lactam after cross-coupling was proven by synthesis of the racemic compounds and comparison by 1H NMR spectroscopy using Pirkle's chiral solvating agent.

[Synthesis of racemic pumiliotoxin C].

Solvent-Free Synthesis of Racemic α-Aminonitriles A

Nevertheless, racemic drugs are often used anyway because the other enaniomer is harmless, and racemic mixtrues are easier(read, cheaper) to synthesize.

A stereocontrolled total synthesis of the indole diterpenoid natural product paspaline is described. Key steps include a highly diastereoselective enzymatic desymmetrization, substrate-directed epoxidation, Ireland-Claisen rearrangement, and diastereotopic group selective C–H acetoxylation to assemble the target with excellent stereofidelity. The route and results described herein outline complementary conceptual disconnections in the arena of steroid natural product synthesis.
