SYNTHESIS OF SMALL MOLECULES INSPIRED BY PHOMOXANTHONE A

Methods, compositions, and kits are provided for synthesizing bioactive chromane, the method including: constructing a tertiary ether stereocenter enantioselectively by catalyzed alkynylation of a substituted chromenone to obtain a chromanone; reducing alkyne and ketone in the chromanone to obtain a chroman; and converting ester to methyl group thereby obtaining chromane.

TMSI-Promoted vinylogous michael addition of siloxyfuran to 2-substituted chromones: A general approach for the total synthesis of chromanone lactone natural products

A concise and facile synthetic protocol for the construction of the 2-γ-lactone chromanone skeleton has been achieved through a TMSI-promoted diastereoselective vinylogous Michael addition of siloxyfuran to 2-substituted chromones. The applicability of this method is demonstrated through the rapid access to the total syntheses of (±)-microdiplodiasone, (±)-lachnone C, and (±)-gonytolides C and G.

Synthesis and Structure-Activity Relationships of Triazaspirodecanone Derivatives as Nociceptin/Orphanin FQ Receptor Ligands

Several spiroxatrine derivatives were synthesized and evaluated as potential NOP receptor ligands. Structural modifications of the 1,4-benzodioxane moiety of spiroxatrine have been the focus of this research project. The structure-activity relationships that emerged indicate that the presence of an H-bond donor group (hydroxyl group) is more favorable for NOP activity when it is positioned α with respect to the CH2 linked to the 1-phenyl-1,3,8-triaza-spiro[4.5]decan-4-one portion. Moreover, cis diastereoisomers of the hydroxyl derivatives4 and 22 show a moderately higher degree of stereoselectivity than trans isomers. In particular, the spiropiperidine derivative cis-4 has submicromolar agonistic activity, and it will be the reference compound for the design and synthesis of new NOP agonists.
