Thus, we anticipate the initial products are 3,4-dichloroaniline and N-methyl, N-methoxy-carbamic acid.

Simple" ester enolates (those derived from mono-esters) can be used to prepare amino acids. The lithium enolate of t-butyl acetate reacted with the methoxy group in 1.185, for example, to give the methyl carbamate of /-butyl 3-aminobutanoate. 

Crich and Rumthao reported a new synthesis of carbazomycin B using a benzeneselenol-catalyzed, stannane-mediated addition of an aryl radical to the functionalized iodocarbamate 835, followed by cyclization and dehydrogenative aromatization (622). The iodocarbamate 835 required for the key radical reaction was obtained from the nitrophenol 784 (609) (see Scheme 5.85). lodination of 784, followed by acetylation, afforded 3,4-dimethyl-6-iodo-2-methoxy-5-nitrophenyl acetate 834. Reduction of 834 with iron and ferric chloride in acetic acid, followed by reaction with methyl chloroformate, led to the iodocarbamate 835. Reaction of 835 and diphenyl diselenide in refluxing benzene with tributyltin hydride and azobisisobutyronitrile (AIBN) gave the adduct 836 in 40% yield, along with 8% of the recovered substrate and 12% of the deiodinated carbamate 837. Treatment of 836 with phenylselenenyl bromide in dichloromethane afforded the phenylselenenyltetrahydrocarbazole 838. Oxidative... 

There were generated glistening crystals of 4-methoxy-N-methylamphetamine hydrochloride (METHYL-MA or DOONE) that weighed, after washing with Et20 and air drying to constant weight, 11.0 g and which had a mp of 177-178 °C. The same base can be made by the action of ethyl chloroformate on 4-MA in the presence of triethylamine to make the carbamate, or the action of formic acid to make the formamide. These can then be reduced with LAH to this same end product.

An interesting acid surrogate is oxazolidine 4.90 (developed by Meyers), which reacted with methoxy carbamate 4.70 (see section 4.3.B.U) in the presence of lithium diisopropylamide and TiCl(OiPr)3 to give 4.91 - Acid hydrolysis converted 4.91 to an acid and esterification gave methyl 3-(N-methylcarbamoyl)-4-methylpentanoate, 4,92 (90% ee, R see chapter five for other enantioselective reactions). In addition, the 3-aminobutanoate derivative was prepared by this method, as was the 3-amino-hex-5-enoic acid derivative. 

The reaction between ethyl Hthiopropiolate and the N-acylpyridinium salt formed by reaction of 4-methoxy-3-methyl-5-(triisopropylsilyl)pyridine 2363 with (+)-frafis-2-(a-cumyl)-cyclohexyl chloroformate (TCC chloro-formate) was the starting point in the synthesis of (-l-)-aUopumihotoxin 267A (1718) by Comins et al. (Scheme 301). The dihydropyridone product (—)- 2364 was obtained diastereoselectively (>96%) before hydrogenation to the saturated ester (+)-2365. However, some epimerization of the methyl substituent was apparent after cleavage of the TCC carbamate with lithium methoxide and cyclization to the indolizidinone (—)-2366 (dr 8 1). Acetoxylation at C-8 with lead tetraacetate was stereoselective, and introduced the acetate from the axial direction, possibly by stereoelec-tronicaUy-controUed intramolecular transfer of acetate from a lead—enol intermediate. The acetoxy product (—)-2367 was protodesilylated with formic acid, after which a one-pot tandem reduction with K-Selectride followed by hthium aluminum hydride gave diol (- -)-2368 with complete...
