  A straightforward synthesis of amides, ureas, and esters is reported by visible-light cross-dehydrogenating coupling (CDC) of aldehydes (or amine carbaldehydes) and amines/R-OTBS ethers by photoredox catalysis. The reaction is found to be general and high yielding. A plausible mechanistic pathway has been proposed for these transformations and is supported by appropriate controlled experiments.

  According to the present invention, it becomes possible to perform a process for converting into an α-substituted cysteine represented by general formula (1) or a salt thereof at low cost and on an industrial scale by employing a process that is routed through a compound represented by general formula (3) to a compound represented by general formula (6). Particularly, by employing a process that is routed through a compound represented by general formula (7-2), it becomes possible to detach a tert-butyl protection group in a simple manner and to produce the compound represented by general formula (1) with high purity. Furthermore, by employing a process that is routed through tert-butylthiomethanol or a process that is routed through a compound represented by general formula (9), it becomes possible to produce a compound represented by general formula (2) without generating bischloromethylether that is an oncogenic substance. In the production of an α-substituted-D-cysteine or a salt thereof, it becomes possible to perform a process for converting the compound represented by general formula (2) into a compound represented by general formula (3S) in one step by allowing an enzyme or the like to act on the compound represented by general formula (2).

  根据本发明，通过采用经由一种化合物（通式（3）表示）到一种通式（6）表示的化合物的过程，可以以低成本和工业化规模进行将其转化为通式（1）表示的α-取代半胱氨酸或其盐的过程。特别是，通过采用经由一种通式（7-2）表示的化合物的过程，可以简单地去除叔丁基保护基，并以高纯度生产通式（1）表示的化合物。此外，通过采用经由叔丁基硫代甲醇或经由一种通式（9）表示的化合物的过程，可以生产通式（2）表示的化合物，而不产生致癌物质双氯甲醚。在生产α-取代-D-半胱氨酸或其盐时，可以通过允许酶或类似物作用于通式（2）表示的化合物，一步将其转化为通式（3S）表示的化合物。

  Ligands for use with catalyst compositions used in hydroformylation reactions are described herein. The ligands are used with various octofluorotoluene or hydrocarbon solvents and achieve an increase in isoselectivity with an increase in temperature, an increase in TON with an increase in temperature, and/or will show isoselectivity that is surprisingly high in comparison to the hydroformylation reactions using common solvents.
