Enantioselective syntheses with titanium carbohydrate complexes. Part 7. Enantioselective allyltitanation of aldehydes with cyclopentadienyldialkoxyallyltitanium complexes

The preparation, analysis, and reactions of novel, highly stereoselective cyclopentadienyldialkoxyallyltitanium reagents, available in both enantiomeric forms, are described. Chiral

Cyclopropenimine Superbases: Competitive Initiation Processes in Lactide Polymerization.

Model studies and comparative experiments with guanidine and phosphazene catalysts revealed the subtle influence of the nature of the superbase on competitive initiation processes.

Pyridine elaboration through organometallic intermediates: regiochemical control and completeness.

This approach relies on organometallic methods, which are both efficacious and extremely flexible as far as the substitution site and the product structure are concerned (86 references).

Macromers by carbocationic polymerization

SummaryThis communication describes the synthesis of two novel CH2=CH-O-headed polyisobutylene (PIB)-based macromers: and The syntheses were worked out by the help of model experiments and

A New Enantioselective Synthesis of the Aminodihydroisocoumarin Moiety of AI-77-B

The aminodihydroisocoumarin moiety of AI-77-B, a gastroprotective substance isolated from Bacillus pumilus AI-77, has been prepared from a convenient chiral synthon of L-erythrose by combination of



Enantiomeric Z- and E-crotyldiisopinocampheylboranes. Synthesis in high optical purity of all four possible stereoisomers of .beta.-methylhomoallyl alcohols

Synthese des 4 stereoisomeres du methyl-3 pentene-4 ol-2 par reaction de (butene-2 diisopinocamphenyl) borane avec l'acetaldehyde

Nuclear Magnetic Resonance Spectroscopy. The Structure of Butenylmagnesium Bromide

Crotyl bromide and α-methylallyl bromide each react with magnesium in ether to yield the same butenyl Grignard reagent, which conceivably could be crotylmagnesium bromide (I), α-methylallyl-magnesium

By the way, the superbase also metalates N,N,N:N’-tetramethylethyleneamine (yields of derivatives up to 45%, L
