Zirconocene dichloride catalysed one-pot synthesis of pyrroles through nitroalkene-enamine assembly

Zirconocene dichloride in an environment-friendly ethanol medium was found to be an efficient catalyst for the synthesis of multi-substituted pyrroles by involving multi-component reactions of amines, β-dicarbonyl compounds and nitroalkenes. The reactions undergo completion easily with high yields and no side-products, allowing the purification of pyrroles in hassle-free and economical manner.

Anti selective glycolate aldol reactions of (S)-4-isopropyl-1-[(R)-1-phenylethyl]imidazolidin-2-one: application towards the asymmetric synthesis of 8-4′-oxyneolignans

The anti selective glycolate aldol reactions of (S)-4-isopropyl-1-[(R)-1-phenylethyl]imidazolidin-2-one auxiliary have been standardized with high yields and excellent diastereoselectivities on various substituted aryl, allyl and alkyl aldehydes. The optimized reaction conditions were employed for the stereoselective synthesis of oxyneolignans.
