上記カルボニル基含有化合物は、「−CO−」構造を持ち、且つカルボニル基のα炭素が水素原子を有する化合物である限り、その種類及び構造に限定はない。上記カルボニル基含有化合物としては、例えば、アルデヒド基、ケトン基、カルボキシル基、アミド基、エステル基、及びカルボン酸無水物基を有する化合物が挙げられる。上記カルボニル基含有化合物は、鎖状構造でもよく、環状構造でもよい。また、上記カルボニル基含有化合物は、飽和化合物でもよく、不飽和化合物でもよい。上記カルボニル基含有化合物として具体的には、例えば、下記一般式(2)で表される化合物(以下、「化合物(2)」という。)が挙げられる。
工程(A)では、水系溶媒及び非水系溶媒からなる二相溶媒中、本発明の塩の存在下、アズラクトン(7)及び化合物(8)を反応させ、化合物(9)を得る。工程(A)は、本発明の反応(上記反応例1)を利用している。よって、工程(A)の内容の詳細は、本発明の反応の項(特に反応例1の項)の説明が妥当する。
