Nicotinic Acid Lariat Ethers: Syntheses, Complexation, and Reduction

Combination of 2-(hydroxymethyl)-5-oxazolinylpyridine 16a with lariat ethers 21 and 23 generated chiral 6-methylnicotinic oxazoline lariat ethers 22 and 24, respectively.Chiral lariat ether 24b by stereoselective metal-directed addition of methylmagnesium bromide was converted to the corresponding enantiomerically enriched N-magnesio-1,4-dihydropyridine 26.Lariat 26 and the nonlariat analogue 31 both reduced α,α,α-trifluoroacetophenone in a NADH model-like reduction to give the S alcohol 32 in low enantiomeric excess.

REGIOSELECTIVE ADDITIONS TO 3-(OXAZOLINYL)PYRIDINE WITH ORGANOLITHIUM REAGENTS

Organolithium reagents have been found to add to the 4- or 6-position in pyridines depending on the nature of the oxazoline present.Thus, methoxy-containing oxazolines lead to the 4-addition product (>95percent), whereas hydroxy-containing oxazolines dire
