An unexpected ring formation in morphine chemistry
ARKIVOC, 2001 Reaction of (7R)-N-benzyl-N-nor-7-bromoneopinone dimethyl acetal (2) with primary or secondary amines (RNH2, R1R2NH) resulted in 9-amino-substituted hasubanan derivatives; in particular, modification of the 9-(2-hydroxyethyl)amino derivative in subsequent steps gave products 8 with a 9-(oxazolidin-2'-one-3'-yl) substituent.

Sol-Gel Chemistry by Ring-Opening Polymerization [PDF]
MRS Proceedings, 1999 ABSTRACTSol-gel processing of materials is plagued by shrinkage during polymerization of the alkoxide monomers and processing (aging and drying) of the resulting gels. We have developed a new class of hybrid organic-inorganic materials based on the solventless ring-opening polymerization (ROP) of monomers bearing the 2,2,5,5-tetramethyl-2,5 ...

Catalytic Cascade Reactions Inspired by Polyketide Biosynthesis
CHIMIA, 2020 Aldol reactions belong to the most important methods for carbon–carbon bond formation and are also involved in one of the most astonishing biosynthetic processes: the biosynthesis of polyketides governed by an extraordinarily sophisticated enzymatic ...

Put a ring on it: application of small aliphatic rings in medicinal chemistry
RSC Medicinal Chemistry, 2021 Aliphatic small rings including cyclopropanes, cyclobutanes, oxetanes, azetidines and bicyclo[1.1.1]pentanes have been increasingly exploited in medicinal chemistry. This review summarises judicious successful application and reported limitations of these ring systems.
