Modified Steglich esterification of (2R)-4-Anilino-1-tert-butoxycarbonyl-2-methyl-4-piperidinecarboxylic acid without using alkylating agents e.g. Iodomethane. With first Steglich looks a bit comlicated with extra problems comparable with clasic alkylation with iodomethane, dimethyl sulfate etc....but once you optimise it you forget about classic alkylations.
Incl. 3 methods . Detection with TLC and GC charts & Yield optimisation of using EDC HCl and HBTU reagent and compariation.
In same manner can be done on various amino acids e.g. Ritalinic acid ....or on other application e.g. esterification of di/mono alkylphosphonic acids
Too saturated/overloaded with phenyl groups ? and excesivelly too bulky structure out of geometrical structure range ? But it seems promising. Stereoisomerism may vary after modification of Truxillic acids especially for 1st and 3rd example to unknown stereoisomers ...
-Synthesis your own dibenzo[b,f][1,4]oxazepine up to w/v 1% solution of combo hybride and PLAY.
Besides of extreme lachrymator potency can be widely used as anti-inflammatory agent for various application. To reverse effect of lachrymation you may want to inject I.M or I.V - TRPA1 antagonist to reverse its effects of lachyrmation and burning sensation rapidly. Perhaps may work with HC-030031 agent (IC50s of 6.2±0.2 and 5.3±0.2 μM) ? or proposed design structure in SMILES : O=C(N(CCC1(CN2)N(C2=O)C(=CC=C2)C=C2)[C@H](C1)C)[C@@H]([C@@H]1C(=CC=C2)C=C2)[C@H]([C@@H]1C(=O)OC(C)C)C(C=CC1)=CC=1 or O=C(OC(C)C)C([C@@H]1C(C=CC2)=CC=2)[C@H](C1CCN(CCC1(CN2)N(C2=O)C(C=CC2)=CC=2)[C@H](C1)C)C(C=CC1)=CC=1
