Fluorous diastereomeric mixture synthesis (FDMS) of hydantoin-fused hexahydrochromeno[4,3-b]pyrroles

Fluorous diastereomeric mixture synthesis (FDMS) is introduced and demonstrated in the synthesis of six diastereomers of hydantoin-fused hexahydrochromeno[4,3-b]pyrroles.

Novel Synthesis of Hexahydrochromeno[4,3-b]pyrrolo[2,1-a]isoquinolines via C-H Functionalization

In present work, an efficient and direct method for the synthesis of hexahydrochromeno[4,3-b]pyrrolo[2,1-a]isoquinolines is reported. This method involves T3P mediated oxidation of alcohols to aldehydes followed by [3+2] cycloaddition to afford hexahydroc

PPh3-mediated intramolecular conjugation of alkyl halides with electron-deficient olefins: Facile synthesis of chromans and relevant analogues

With the mediation of phosphine, the direct intramolecular coupling of two electrophiles-alkyl halides with electron-deficient olefins-has been successfully realized in an intramolecular conjugate addition manner. The reaction provides a new approach for
