Sulfenyl groups are attracting interest as masking/protectinggroups for pyrroles. A facile one-step synthesis of sulfenyl pyrroles,involving the reaction of pyrroles with N-(aryl-and alkyl-thio)phthalimides in the presence of MgBr 2 ,is reported and

The Thompson group aims to further the chemistry of pyrroles, dipyrrins and prodigiosenes. This micro-review discusses each of these research areas in turn, focussing on our achievements thus far.

The asymmetric oxidation of prochiral 2-(arylsulfenyl)pyrroles has been investigated. A marked electronic effect within the substrate significantly influenced the degree of enantioselectivity obtained, with very high enantio selectivity being obtaine

The aldol reaction of tetrahydro-4H-thiopyranone with 1,4-dioxa-8-thiaspiro[4.5]decane-6-carboxaldehyde (I) gives four possible diastereomeric adducts (II). Aldol reactions of I with each of the diastereomers of II and their corresponding methoxymeth

Meso 1,9-diketones (six to seven stereocenters) are readily obtained by stepwise or simultaneous two-directional aldol reactions of tetrahydro-4H-thiopyran-4-one with a thiopyran-derived aldehyde or dialdehyde. Enantioselective enolizations of these
