A compound of formula I wherein: n is 1 or 2: p is 0 or 1; R1 is optionally one or more halo or methyl groups; R2a and R2b are independently selected from the group consisting of: (i) F; (ii) H; (iii) Me; and (iv) CH2OH; R2c and R2d are independently selected from the group consisting of: (i) F; (ii) H; (iii) Me; and (iv) CH2OH; R3a and R3b are independently selected from H and Me; R4 is either H or Me; R5 is either H or Me; R6a and R6b are independently selected from H and Me; A is either (i) optionally substituted phenyl; (ii) optionally substituted naphthyl; or (iii) optionally substituted C5-12 heteroaryl.
Ethynylbenziodazolones (EBZ) as Electrophilic Alkynylation Reagents for the Highly Enantioselective Copper‐Catalyzed Oxyalkynylation of Diazo Compounds
radicals and nucleophiles, yet they present limited possibilities for further structure and reactivity modification. Herein, the first synthesis is reported for the corresponding ethynylbenziodazolone (EBZ) reagents, in which the oxygen atom in the iodoheterocycle is replaced by a nitrogen atom. The substituent on the nitrogen enables further fine‐tuning of the reagent structure and reactivity. EBZ reagents

The present invention relates to compounds useful as catalysts in asymmetric synthesis of chiral compounds, methods for the synthesis of said catalysts, and methods for synthesizing chiral compounds with high enantioselectivity.
A method for producing camphorsultam, which includes the following steps 1 to 4:
Step 1: reacting camphorsulfonic acid with a halogenation agent to give camphorsulfonyl halide,
Step 2: reacting the camphorsulfonyl halide with ammonia to give camphorsulfonamide,
Step 3: subjecting the camphorsulfonamide to dehydration and ring closure to give camphorsulfonimine, and
Step 4: reducing the camphorsulfonimine with sodium borohydride in an aqueous isopropanol solution. According to this invention, camphorsultam and intermediates thereof can be obtained by an industrial method which is comparatively safe to the environment and human body, economical, and which is simple and easy.

Two syntheses are provided; one for the preparation of (3R,4R)-4-(hydroxymethyl)pyrrolidin-3-ol, and other for the preparation of (3S,4R)-4-(hydroxymethyl)pyrrolidin-3-ol. (3R,4R)-4-(hydroxymethyl)pyrrolidin-3-ol is prepared using the achiral ylide prepared from benzylamine instead of phenethylamine (Scheme 3) which provides a crystalline intermediate. The synthesis of (3S,4R)-4-(hydroxymethyl)pyrrolidin-3-ol is achieved from (S)-diethylmalate as described in Scheme 4. A process for preparing camphor sultam is also provided.
