Ring appendages

Appendage based strategies may be divided into disconnective and reconnective. The latter may be further partitioned into ring appendage - ring [Pg.16]

ACS Symposium Series American Chemical Society Washington, DC, 1977. [Pg.16]

THE CHEMISTRY PACKAGES OF LHASA Functional Group Based Transforms [Pg.17]

Two group transforms are keyed specifically by two functional groups with a path of predetermined length between them. Examples of these are shown below. [Pg.17]

One group transforms are similar but are keyed by one specific group with an associated path (not as [Pg.17]

If the disconnection of a bond found to be strategic by criteria 1-3 produces a new ring appendage bearing stereocenters, those centers should be removed if possible (by stereocontrolled transforms) before the disconnection is made. [Pg.42]

Additional keying information can come from certain other structural features which are present in a retron- or partial-retron-containing substructure. These ancillary keying elements can consist of functional groups, stereocenters, rings or appendages. Consider target structure 5... [Pg.7]

Algorithms for machine-generated syntheses by application of connective transforms to target structures containing appendages, medium-sized rings, etc. have been described. ... [Pg.75]

Appendage. A structural subunit consisting of one or more carbon atoms and their substituents which is bonded to a ring or functional group origin. [Pg.96]

Tricyclohexaprenol, a possible forerunner of sterols in the evolution of biomembranes, was synthesized by construction of the cyclic network in one step using cation-olefin tricyclization and subsequent stereocontroUed attachment of the Cio appendage to ring C. [Pg.195]
