We report herein the development of two efficient synthetic routes for the preparation of a key fragment required for the synthesis of potent drug candidates of Hepatitis B virus. The ethyl 3-fluoro-1-H-pyrrole-2-carboxylate scaffold was synthesized from readily available starting materials in good overall yields. The scalability of one of the developed routes was demonstrated and afforded the desired target in good yield and excellent purity (99%).

The DNA repair enzyme AAG has been shown in mice to promote tissue necrosis in response to ischaemic reperfusion or treatment with alkylating agents. A chemical probe inhibitor is required for investigations of the biological mechanism causing this phenomenon and as a lead for drugs that are potentially protective against tissue damage from organ failure and transplantation, and alkylative chemotherapy. Herein, we describe the rationale behind the choice of arylmethylpyrrolidines as appropriate aza-nucleoside mimics for an inhibitor followed by their synthesis and the first use of a microplate-based assay for quantification of their inhibition of AAG. We finally report the discovery of an imidazol-4-ylmethylpyrrolidine as a fragment-sized, weak inhibitor of AAG.

Paragraph 0028; 0029; 0034; 0035; 0040; 0041, (2018/12/13)
The invention provides a novel method for preparing 3-(3-chloropropyl)-4-oxopyrrolidine-1-ethyl carboxylate, aiming at solving the technical problems of a traditional 3-(3-chloropropyl)-4-oxopyrrolidine-1-ethyl carboxylate synthesis method in the prior art that a flow is complicated, the environmental hazards are great, the safety is low and the yield is low. The technology takes glycine ethyl ester and ethyl acrylate as starting raw materials, and steps of taking benzylamine as a raw material and carrying out debenzylation in a subsequent process are reduced; a process for preparing the 3-(3-chloropropyl)-4-oxopyrrolidine-1-ethyl carboxylate is greatly simplified; an existing technology needs 6-step reaction, and the technology only needs 5-step reaction, so that the operation is simplified and a production period is shortened; the method is applicable to large-scale industrial production. The technology does not take the benzylamine as the starting raw material, and the generation ofa cancer-causing high-hazard substance, i.e., benzyl chloride, is directly stopped from the source; harms to an ecological environment and body health of people are effectively avoided; a reaction process is safe and accords with environmental protection requirements of China better; the total yield is greatly improved and the yield is greater than or equal to 50 percent.

supporting information, p. 8271 - 8274 (2016/07/06)
Piperazinedione 13, representing the BC rings of the anti-prostate cancer fungal metabolite MPC1001, was prepared by a route in which a sulfur-stabilized carbanion derived from 22 cyclizes onto the terminal ester of the pendant chain attached to N1. Another model, 14, was synthesized by cyclization of an α-ketoamide nitrogen onto an ester; 14 represents the BC rings of MPC1001F.
