Design and development of bioinspired guanine-based organic catalyst for asymmetric catalysis

Design, preparation, and studies of a family of new organic catalysts are presented. The design of the catalysts is inspired by the ability of DNA nucleobases to develop precise and explicit hydrogen bonds. We have shown that this phenomenon can be used to create a useful organic catalyst that demonstrates a recognition pattern similar to those of common organic substrates. A selected bifunctional catalyst based on a guanine structure has been shown to catalyze the conjugate addition of 1,3-dicarbonyl compounds to various nitroalkenes, providing the products in good yields and enantioselectivities.

Use of optically active cyclic N,N-dialkyl aminals in asymmetric induction.

[reaction: see text]Cyclization of the optically active ketone N,N-dialkyl aminals A affords the diastereomer B as the major product with diastereoselectivities ranging from nearly 1:1 to essentially 100:0 depending on the cyclization studied.

Stereospecific conversion of chiral 1,2-cyclic sulfates to chiral imidazolines

The one pot preparation of imidazolines from 1,2-cyclic sulfates is reported. Amidines react with cyclic sulfates to give zwitterionic intermediates, and subsequent intramolecular cyclization affords imidazolines. The preparation of enantiopure stilbene d
