A series of spiro-azetidines and azetidinones has been evaluated as novel blockers of the T-type calcium channel (CaV3.2) which is a new therapeutic target for the potential treatment of both inflammatory and neuropathic pain. Confirmation and optimization of the potency, selectivity and DMPK properties of leads will be described.

methodology is compatible with a wide-range of aliphatic linear, branched, and ester functionalized N-substituents. Unexpectedly, the formation of regioisomers featuring a 1,2,3-contiguous substitution pattern in the aromatic ring of the indene core was observed. Three distinct combinatorial libraries with a total of 111 of members were synthesized, and 80 highly substituted dihydroindenoisoquinolines structurally

The reactivity of 3‐oxo‐β‐lactams with respect to primary amines was investigated in depth. Depending on the specific azetidin‐2‐one C4 substituent, this reaction was shown to selectively produce 3‐imino‐β‐lactams (through dehydration), α‐aminoamides (through CO elimination), or ethanediamides (through an unprecedented C3−C4 ring opening). In addition to the experimental results, the mechanisms and
Thiazolidinones Derived from Dynamic Systemic Resolution of Complex Reversible-Reaction Networks

日期:2014.3.17
A complex dynamic system based on a network of multiple reversible reactions has been established. The network was applied to a dynamic systemic resolution protocol based on kinetically controlled lipase‐catalyzed transformations. This resulted in the formation of cyclized products, where two thiazolidinone compounds were efficiently produced from a range of potential transformations.
