An efficient generalmethod for the consecutive introduction of two alkyl groups to the α carbon of a ketone carbonyl has been developed, making use of the lithium naphthalenide induced reductive alkylation of an α-cyano ketone system as a key operation.

A new procedure for the regiocontrolled synthesis of α-(phenylsulfanyl) carbonylcompounds has been developed, making use of lithium naphthalenide induced reductive sulfenylation of α-cyano carbonylcompounds as a key operation. Through this protocol, a variety of a-(phenylsulfanyl) carbonylcompounds has been prepared in moderate to high yields. The completely regioselective sulfenylation was observed

α-phenylseleno ketones has been developed, making use of the lithium naphthalenide induced reductive selenenylation of the α-cyano ketone system as a key operation. Moreover, seleno ketones thus generated in situ, upon subsequent treatment with hydrogen peroxide and acetic acid, could be further converted into the corresponding enones with a high degree of regioselectivity, presumably due to the lithium salt
